RC.CONF(5)		       File Formats Manual		      RC.CONF(5)

NAME
     rc.conf -- system configuration information

DESCRIPTION
     The  file	rc.conf  contains  descriptive	information about the local host
     name, configuration details for any potential network interfaces and  which
     services  should be started up at system initial boot time.  In new instal-
     lations, the rc.conf file is generally initialized by the system  installa-
     tion utility.

     The purpose of rc.conf is not to run commands or perform system startup ac-
     tions  directly.	Instead,  it  is included by the various generic startup
     scripts in /etc which conditionalize their internal  actions  according  to
     the settings found there.

     The  /etc/rc.conf	file  is  included  from the file /etc/defaults/rc.conf,
     which specifies the default settings for all the  available  options.   Op-
     tions  need only be specified in /etc/rc.conf when the system administrator
     wishes to override these defaults.  The file /etc/defaults/vendor.conf  al-
     lows  vendors to override FreeBSD defaults.  The file /etc/rc.conf.local is
     used to override settings in /etc/rc.conf for historical reasons.

     The sysrc(8) command provides a scripting interface to modify system config
     files.

     In addition to /etc/rc.conf.local you can also place smaller  configuration
     files   for   each   rc(8)   script  in  the  /etc/rc.conf.d  directory  or
     <dir>/rc.conf.d directories specified in local_startup, which will  be  in-
     cluded  by  the load_rc_config function.  For jail configurations you could
     use the file /etc/rc.conf.d/jail to store jail specific  configuration  op-
     tions.    If  local_startup  contains  /usr/local/etc/rc.d  and  /opt/conf,
     /usr/local/rc.conf.d/jail and /opt/conf/rc.conf.d/jail will be loaded.   If
     <dir>/rc.conf.d/<name>  is  a directory, all of files in the directory will
     be loaded.  Also see the rc_conf_files variable below.

     Options are set with "name=value" assignments that use sh(1)  syntax.   The
     following list provides a name and short description for each variable that
     can be set in the rc.conf file:

     rc_debug	 (bool) If set to "YES", enable output of debug messages from rc
		 scripts.   This  variable can be helpful in diagnosing mistakes
		 when editing or integrating new scripts.  Beware that this pro-
		 duces copious output to the terminal and syslog(3).

     rc_info	 (bool) If set to "NO", disable informational messages from  the
		 rc scripts.  Informational messages are displayed when a condi-
		 tion  that is not serious enough to warrant a warning or an er-
		 ror occurs.

     rc_startmsgs
		 (bool) If set to "YES", show "Starting foo:" when faststart  is
		 used (e.g., at boot time).

     early_late_divider
		 (str)	The name of the script that should be used as the delim-
		 iter between the "early" and "late" stages of the boot process.
		 The early stage should contain all the services needed  to  get
		 the  disks (local or remote) mounted so that the late stage can
		 include scripts contained in  the  directories  listed  in  the
		 local_startup	variable (see below).  Thus, the two likely can-
		 didates for this value are mountcritlocal for the typical  sys-
		 tem,  and  mountcritremote if the system needs remote file sys-
		 tems mounted to get access to	the  local_startup  directories;
		 for example when /usr/local is NFS mounted.  For rc.conf within
		 a jail(8) NETWORKING is likely to be an appropriate value.  Ex-
		 treme care should be taken when changing this value, and before
		 changing  it  one  should ensure that there are adequate provi-
		 sions to recover from a failed boot (such as  physical  contact
		 with the machine, or reliable remote console access).

     always_force_depends
		 (bool)  Various  rc.d	scripts use the force_depend function to
		 check whether required services are  already  running,  and  to
		 start	them  if  necessary.   By  default during boot time this
		 check is  bypassed  if  the  required	service  is  enabled  in
		 /etc/rc.conf[.local].	 Setting  this	option	will bypass that
		 check at boot time and always test whether or not  the  service
		 is  actually  running.   Enabling  this option is likely to in-
		 crease your boot time if services are enabled that utilize  the
		 force_depend check.

     <name>_chroot
		 (str) chroot(8) to this directory before running the service.

     <name>_user
		 (str) Run the service under this user account.

     <name>_group
		 (str) Run the chrooted service under this system group.  Unlike
		 the _user setting, this setting has no effect if the service is
		 not chrooted.

     <name>_fib  (int) The setfib(1) value to run the service under.

     <name>_nice
		 (int) The nice(1) value to run the service under.

     apm_enable  (bool) If set to "YES", enable support for Automatic Power Man-
		 agement with the apm(8) command.

     apmd_enable
		 (bool)  Run  apmd(8)  to  handle APM event from userland.  This
		 also enables support for APM.

     apmd_flags  (str) If apmd_enable is set to "YES", these are  the  flags  to
		 pass to the apmd(8) daemon.

     devd_enable
		 (bool)  Run  devd(8) to handle device added, removed or unknown
		 events from the kernel.

     ddb_enable  (bool) Run ddb(8) to install ddb(4) scripts at boot time.

     ddb_config  (str) Configuration file for ddb(8).  Default /etc/ddb.conf.

     devmatch_enable
		 (bool) If set to "NO", disable auto-loading of  kernel  modules
		 with devmatch(8).

     devmatch_blacklist
		 (str)	A  whitespace-separated list of kernel modules to be ig-
		 nored by devmatch(8).

     kld_list	 (str) A whitespace-separated list of  kernel  modules	to  load
		 right after the local disks are mounted, without any .ko exten-
		 sion  or  path.   Loading  modules  at  this  point in the boot
		 process is much faster than doing it via /boot/loader.conf  for
		 those modules not necessary for mounting local disks.

     kldxref_enable
		 (bool)  Set  to "NO" by default.  Set to "YES" to automatically
		 rebuild linker.hints files with kldxref(8) at boot time.

     kldxref_clobber
		 (bool) Set to "NO" by default.  If kldxref_enable is true, set-
		 ting to "YES" will overwrite  existing  linker.hints  files  at
		 boot time.  Otherwise, only missing linker.hints files are gen-
		 erated.

     kldxref_module_path
		 (str)	Empty  by default.  A semi-colon (`;') delimited list of
		 paths containing kld(4) modules.  If empty, the contents of the
		 kern.module_path sysctl(8) are used.

     powerd_enable
		 (bool) If set to "YES", enable the system power control  facil-
		 ity with the powerd(8) daemon.

     powerd_flags
		 (str)	If powerd_enable is set to "YES", these are the flags to
		 pass to the powerd(8) daemon.

     tmpmfs	 Controls the creation of a /tmp  memory  file	system.   Always
		 happens  if  set to "YES" and never happens if set to "NO".  If
		 set to anything else, a memory file system is created	if  /tmp
		 is not writable.

     tmpsize	 Controls the size of a created /tmp memory file system.

     tmpmfs_flags
		 Extra	options  passed  to the mdmfs(8) utility when the memory
		 file system for /tmp is created.  The default	is  "-S",  which
		 inhibits  the	use  of  softupdates on /tmp so that file system
		 space is freed without delay after file truncation or deletion.
		 See mdmfs(8) for other options you can use in tmpmfs_flags.

     varmfs	 Controls the creation of a /var  memory  file	system.   Always
		 happens  if  set to "YES" and never happens if set to "NO".  If
		 set to anything else, a memory file system is created	if  /var
		 is not writable.

     varsize	 Controls the size of a created /var memory file system.

     varmfs_flags
		 Extra	options  passed  to the mdmfs(8) utility when the memory
		 file system for /var is created.  The default	is  "-S",  which
		 inhibits  the	use  of  softupdates on /var so that file system
		 space is freed without delay after file truncation or deletion.
		 See mdmfs(8) for other options you can use in varmfs_flags.

     populate_var
		 Controls the automatic population of the /var file system.  Al-
		 ways happens if set to "YES" and never happens if set to  "NO".
		 If  set  to  anything	else, a memory file system is created if
		 /var is not writable.	Note that this process	requires  access
		 to  certain  commands	in /usr before /usr is mounted on normal
		 systems.

     cleanvar_enable
		 (bool) Clean the /var directory.

     local_startup
		 (str) List of directories to search for startup script files.

     script_name_sep
		 (str) The field separator to use for breaking down the list  of
		 startup script files into individual filenames.  The default is
		 a  space.   It is not necessary to change this unless there are
		 startup scripts with names containing spaces.

     hostapd_enable
		 (bool) Set to "YES" to start hostapd(8) at system boot time.

     hostname	 (str) The fully qualified domain name (FQDN) of  this	host  on
		 the  network.	This should almost certainly be set to something
		 meaningful,  even  if	there  is  no  network	connection.   If
		 dhclient(8) is used to set the hostname via DHCP, this variable
		 should  be  set to an empty string.  Within a jail(8) the host-
		 name is generally already set and this variable may be  absent.
		 If  this  value  remains  unset when the system is done booting
		 your  console	login  will  display  the  default  hostname  of
		 "Amnesiac".

     nisdomainname
		 (str)	The  NIS domain name of this host, or "NO" if NIS is not
		 used.

     dhclient_program
		 (str) Path to the  DHCP  client  program  (/sbin/dhclient,  the
		 OpenBSD DHCP client, is the default).

     dhclient_flags
		 (str) Additional flags to pass to the DHCP client program.  For
		 the  OpenBSD DHCP client, see the dhclient(8) manpage for a de-
		 scription of the command line options available.

     dhclient_flags_<iface>
		 Additional flags to pass to the DHCP client program running  on
		 iface	 only.	  When	 specified,   this   variable  overrides
		 dhclient_flags.

     background_dhclient
		 (bool) Set to "YES" to start the  DHCP  client  in  background.
		 This can cause trouble with applications depending on a working
		 network, but it will provide a faster startup in many cases.

     background_dhclient_<iface>
		 When specified, this variable overrides the background_dhclient
		 variable for interface iface only.

     synchronous_dhclient
		 (bool)  Set  to  "YES"  to  start  dhclient(8) synchronously at
		 startup.  This behavior can be overridden  on	a  per-interface
		 basis	  by	replacing    the    "DHCP"    keyword	in   the
		 ifconfig_<interface> variable with "SYNCDHCP" or "NOSYNCDHCP".

     defaultroute_delay
		 (int) When set to a positive value, wait up to this long  after
		 configuring  DHCP  interfaces at startup to give the interfaces
		 time to receive a lease.

     firewall_enable
		 (bool) Set to "YES" to load firewall rules at startup.  If  the
		 kernel  was not built with options IPFIREWALL, the ipfw.ko ker-
		 nel module will be loaded.  See also ipfilter_enable.

     firewall_script
		 (str) This variable specifies the full  path  to  the	firewall
		 script to run.  The default is /etc/rc.firewall.

     firewall_type
		 (str)	 Names	 the   firewall   type	from  the  selection  in
		 /etc/rc.firewall, or the file which contains the local firewall
		 ruleset.  Valid selections from /etc/rc.firewall are:

		 open	 unrestricted IP access
		 closed  all IP services disabled, except via "lo0"
		 client  basic protection for a workstation
		 simple  basic protection for a LAN.

		 If a filename is specified, the full path must be given.

     firewall_quiet
		 (bool) Set to "YES" to disable the display of firewall rules on
		 the console during boot.

     firewall_logging
		 (bool) Set to "YES" to enable firewall event logging.	This  is
		 equivalent to the IPFIREWALL_VERBOSE kernel option.

     firewall_logif
		 (bool)  Set  to "YES" to create pseudo interface ipfw0 for log-
		 ging.	For more details, see ipfw(8) manual page.

     firewall_flags
		 (str) Flags passed to	ipfw(8)  if  firewall_type  specifies  a
		 filename.

     firewall_coscripts
		 (str)	List of executables and/or rc scripts to run after fire-
		 wall starts/stops.  Default is empty.

     firewall_nat_enable
		 (bool) The ipfw(8) equivalent of natd_enable.	Setting this  to
		 "YES"	will automatically load the ipfw(8) NAT kernel module if
		 firewall_enable is also set to "YES".

     firewall_nat_interface
		 (str) The ipfw(8) equivalent of natd_interface.   This  is  the
		 name  of the public interface or IP address on which kernel NAT
		 should run.

     firewall_nat_flags
		 (str) Additional configuration parameters for kernel NAT should
		 be placed here.

     firewall_nat64_enable
		 (bool) Setting  this  to  "YES"  will	automatically  load  the
		 ipfw(8)  NAT64  kernel module if firewall_enable is also set to
		 "YES".

     firewall_nptv6_enable
		 (bool) Setting  this  to  "YES"  will	automatically  load  the
		 ipfw(8)  NPTv6  kernel module if firewall_enable is also set to
		 "YES".

     firewall_pmod_enable
		 (bool) Setting  this  to  "YES"  will	automatically  load  the
		 ipfw(8)  pmod	kernel	module if firewall_enable is also set to
		 "YES".

     dummynet_enable
		 (bool) Setting this to "YES" will automatically load  the  dum-
		 mynet(4) module if firewall_enable is also set to "YES".

     ipfw_netflow_enable
		 (bool)  Setting  this	to "YES" will enable netflow logging via
		 ng_netflow(4)

		 By default a ipfw rule is inserted and all packets  are  dupli-
		 cated	with  the  ngtee command and netflow packets are sent to
		 127.0.0.1 on the netflow port using protocol version 5.

     ipfw_netflow_hook
		 (int) netflow hook name, must be numerical (default 9995).

     ipfw_netflow_rule
		 (int) ipfw rule number (default 1000).

     ipfw_netflow_ip
		 (str) Destination server ip for receiving netflow data (default
		 127.0.0.1).

     ipfw_netflow_port
		 (int) Destination server port for receiving netflow  data  (de-
		 fault 9995).

     ipfw_netflow_version
		 (int)	Do  not set for using version 5 of the netflow protocol,
		 set it to 9 for using version 9.

     ipfw_netflow_fib
		 (int) Only match packet in FIB ipfw_netflow_fib (default is un-
		 defined meaning all FIBs).

     natd_program
		 (str) Path to natd(8).

     natd_enable
		 (bool) Set to "YES" to enable	natd(8).   firewall_enable  must
		 also  be set to "YES", and divert(4) sockets must be enabled in
		 the kernel.  If the kernel was not built with options IPDIVERT,
		 the ipdivert.ko kernel module will be loaded.

     natd_interface
		 (str) This is the name of the public interface on which natd(8)
		 should run.  The interface may be given as an interface name or
		 as an IP address.

     natd_flags  (str) Additional natd(8) flags should be placed here.	 The  -n
		 or -a flag is automatically added with the above natd_interface
		 as an argument.

     ipfilter_enable
		 (bool)  Set  to "NO" by default.  Setting this to "YES" enables
		 ipf(8) packet filtering.

		 Typical usage will require putting

		 ipfilter_enable="YES"
		 ipnat_enable="YES"
		 ipmon_enable="YES"
		 ipfs_enable="YES"

		 into	 /etc/rc.conf	 and	editing    /etc/ipf.rules    and
		 /etc/ipnat.rules appropriately.

		 Note that ipfilter_enable and ipnat_enable can be enabled inde-
		 pendently.   ipmon_enable and ipfs_enable both require at least
		 one of ipfilter_enable and ipnat_enable to be enabled.

		 Having

		 options IPFILTER
		 options IPFILTER_LOG
		 options IPFILTER_DEFAULT_BLOCK

		 in the kernel configuration file is a good idea, too.

     ipfilter_program
		 (str) Path to ipf(8) (default /sbin/ipf).

     ipfilter_rules
		 (str) Set to /etc/ipf.rules by default.  This variable contains
		 the name of the filter rule definition file.  The file  is  ex-
		 pected to be readable for the ipf(8) command to execute.

     ipv6_ipfilter_rules
		 (str)	Set  to  /etc/ipf6.rules by default.  This variable con-
		 tains the IPv6 filter rule definition file.  The  file  is  ex-
		 pected to be readable for the ipf(8) command to execute.

     ipfilter_flags
		 (str) Empty by default.  This variable contains flags passed to
		 the ipf(8) program.

     ipnat_enable
		 (bool)  Set  to "NO" by default.  Set it to "YES" to enable ip-
		 nat(8) network address translation.  See ipfilter_enable for  a
		 detailed discussion.

     ipnat_program
		 (str) Path to ipnat(8) (default /sbin/ipnat).

     ipnat_rules
		 (str)	Set  to /etc/ipnat.rules by default.  This variable con-
		 tains the name of the file holding the network address transla-
		 tion definition.  This file is expected to be readable for  the
		 ipnat(8) command to execute.

     ipnat_flags
		 (str) Empty by default.  This variable contains flags passed to
		 the ipnat(8) program.

     ipmon_enable
		 (bool)  Set  to "NO" by default.  Set it to "YES" to enable ip-
		 mon(8) monitoring (logging ipf(8) and ipnat(8)  events).   Set-
		 ting	this   variable   needs   setting   ipfilter_enable   or
		 ipnat_enable too.  See ipfilter_enable for a  detailed  discus-
		 sion.

     ipmon_program
		 (str) Path to ipmon(8) (default /sbin/ipmon).

     ipmon_flags
		 (str)	Set  to  "-Ds" by default.  This variable contains flags
		 passed to the ipmon(8) program.  Another typical example  would
		 be "-D /var/log/ipflog" to have ipmon(8) log directly to a file
		 bypassing  syslogd(8).  Make sure to adjust /etc/newsyslog.conf
		 in such case like this:

		 /var/log/ipflog  640  10  100	*  Z  /var/run/ipmon.pid

     ipfs_enable
		 (bool) Set to "NO" by default.   Set  it  to  "YES"  to  enable
		 ipfs(8)  saving the filter and NAT state tables during shutdown
		 and reloading them during startup again.  Setting this variable
		 needs setting ipfilter_enable or  ipnat_enable  to  "YES"  too.
		 See  ipfilter_enable  for  a detailed discussion.  Note that if
		 kern_securelevel is set to 3, ipfs_enable cannot  be  used  be-
		 cause	the  raised securelevel will prevent ipfs(8) from saving
		 the state tables at shutdown time.

     ipfs_program
		 (str) Path to ipfs(8) (default /sbin/ipfs).

     ipfs_flags  (str) Empty by default.  This variable contains flags passed to
		 the ipfs(8) program.

     pf_enable	 (bool) Set to "NO" by default.  Setting this to  "YES"  enables
		 pf(4) packet filtering.

		 Typical usage will require putting

		       pf_enable="YES"

		 into	/etc/rc.conf  and  editing  /etc/pf.conf  appropriately.
		 Adding

		       device pf

		 builds support for pf(4) into the kernel, otherwise the  kernel
		 module will be loaded.

     pf_rules	 (str)	 Path  to  pf(4)  ruleset  configuration  file	(default
		 /etc/pf.conf).

     pf_program  (str) Path to pfctl(8) (default /sbin/pfctl).

     pf_flags	 (str) If pf_enable is set to "YES", these flags are  passed  to
		 the pfctl(8) program when loading the ruleset.

     pflog_enable
		 (bool)  Set  to "NO" by default.  Setting this to "YES" enables
		 pflogd(8) which logs packets from the pf(4) packet filter.

     pflog_logfile
		 (str) If pflog_enable is  set	to  "YES"  this  controls  where
		 pflogd(8)  stores  the logfile (default /var/log/pflog).  Check
		 /etc/newsyslog.conf to adjust logfile rotation for this.

     pflog_program
		 (str) Path to pflogd(8) (default /sbin/pflogd).

     pflog_flags
		 (str) Empty by  default.   This  variable  contains  additional
		 flags passed to the pflogd(8) program.

     pflog_instances
		 (str)	If  logging  to  more than one pflog(4) interface is de-
		 sired, pflog_instances is set to  the	list  of  pflogd(8)  in-
		 stances  that	should	be  started  at  system  boot  time.  If
		 pflog_instances is set, for each  whitespace-separated  element
		 in  the  list, <element>_dev and <element>_logfile elements are
		 assumed to exist.  <element>_dev must contain the pflog(4)  in-
		 terface   to  be  watched  by	the  named  pflogd(8)  instance.
		 <element>_logfile must contain the name  of  the  logfile  that
		 will be used by the pflogd(8) instance.

     ftpproxy_enable
		 (bool)  Set  to "NO" by default.  Setting this to "YES" enables
		 ftp-proxy(8) which supports the pf(4) packet filter  in  trans-
		 lating ftp connections.

     ftpproxy_flags
		 (str)	Empty  by  default.   This  variable contains additional
		 flags passed to the ftp-proxy(8) program.

     ftpproxy_instances
		 (str) Empty by default.  If multiple instances of  ftp-proxy(8)
		 are  desired  at boot time, ftpproxy_instances should contain a
		 whitespace-separated list of instance names.  For each  element
		 in  the  list,  a  variable named <element>_flags should be de-
		 fined, containing the command-line flags to be  passed  to  the
		 ftp-proxy(8) instance.

     pfsync_enable
		 (bool)  Set  to "NO" by default.  Setting this to "YES" enables
		 exposing pf(4) state changes to other hosts over the network by
		 means of pfsync(4).  The pfsync_syncdev variable must	also  be
		 set then.

     pfsync_syncdev
		 (str)	Empty  by  default.  This variable specifies the name of
		 the network interface pfsync(4)  should  operate  through.   It
		 must be set accordingly if pfsync_enable is set to "YES".

     pfsync_syncpeer
		 (str)	Empty  by  default.   This variable is optional.  By de-
		 fault, state change messages are sent out on  the  synchronisa-
		 tion  interface using IP multicast packets.  The protocol is IP
		 protocol  240,  PFSYNC,  and  the  multicast  group   used   is
		 224.0.0.240.	When  a  peer  address	is  specified  using the
		 pfsync_syncpeer option, the peer address is used as a	destina-
		 tion  for  the pfsync traffic, and the traffic can then be pro-
		 tected using ipsec(4).  See the pfsync(4) manpage for more  de-
		 tails about using ipsec(4) with pfsync(4) interfaces.

     pfsync_ifconfig
		 (str)	Empty  by default.  This variable can contain additional
		 options to be passed to the ifconfig(8) command used to set  up
		 pfsync(4).

     tcp_extensions
		 (bool)  Set to "YES" by default.  Setting this to "NO" disables
		 certain TCP options as described by RFC 1323.	Setting this  to
		 "NO"  might  help remedy such problems with connections as ran-
		 domly hanging or other weird behavior.   Some	network  devices
		 are known to be broken with respect to these options.

     log_in_vain
		 (int)	 Set   to   0  by  default.   The  sysctl(8)  variables,
		 net.inet.tcp.log_in_vain and net.inet.udp.log_in_vain,  as  de-
		 scribed in tcp(4) and udp(4), are set to the given value.

     tcp_keepalive
		 (bool)  Set  to "YES" by default.  Setting to "NO" will disable
		 probing idle TCP connections to verify that the peer  is  still
		 up and reachable.

     tcp_drop_synfin
		 (bool) Set to "NO" by default.  Setting to "YES" will cause the
		 kernel  to  ignore  TCP  frames  that have both the SYN and FIN
		 flags set.  This prevents OS fingerprinting, but may break some
		 legitimate applications.

     icmp_drop_redirect
		 (bool) Set to "AUTO" by default.  This setting will be  identi-
		 cal  to  "YES",  if a dynamicrouting daemon is enabled, because
		 redirect processing may  cause  performance  issues  for  large
		 routing  tables.   If	no such service is enabled, this setting
		 behaves like a "NO".  Setting to "YES" will cause the kernel to
		 ignore ICMP REDIRECT packets.	Setting to "NO" will  cause  the
		 kernel  to process ICMP REDIRECT packets.  Refer to icmp(4) for
		 more information.

     icmp_log_redirect
		 (bool) Set to "NO" by default.  Setting to "YES" will cause the
		 kernel to log ICMP REDIRECT packets.  Note that  the  log  mes-
		 sages	are not rate-limited, so this option should only be used
		 for troubleshooting networks.	Refer to icmp(4) for more infor-
		 mation.

     icmp_bmcastecho
		 (bool) Set to "YES" to respond to broadcast or  multicast  ICMP
		 ping packets.	Refer to icmp(4) for more information.

     ip_portrange_first
		 (int) If not set to "NO", this is the first port in the default
		 portrange.  Refer to ip(4) for more information.

     ip_portrange_last
		 (int)	If not set to "NO", this is the last port in the default
		 portrange.  Refer to ip(4) for more information.

     network_interfaces
		 (str) Set to the list of network  interfaces  to  configure  on
		 this  host  or "AUTO" (the default) for all current interfaces.
		 Setting the network_interfaces variable to anything other  than
		 the  default  is deprecated.  Interfaces that the administrator
		 wishes to store configuration for, but not start at boot should
		 be   configured   with   the	"NOAUTO"   keyword   in    their
		 ifconfig_<interface> variables as described below.

		 An  ifconfig_<interface>  variable is also assumed to exist for
		 each value of interface.  When an interface name  contains  any
		 of  the  characters  ".-/+"  they  are translated to "_" before
		 lookup.  The variable can contain arguments to ifconfig(8),  as
		 well  as  special  case-insensitive  keywords	described below.
		 Such keywords are removed before passing the  value  to  ifcon-
		 fig(8) while the order of the other arguments is preserved.

		 It is possible to add IP alias entries using ifconfig(8) syntax
		 with  the  address  family keyword such as inet.  Assuming that
		 the interface in question was em0, it might look something like
		 this:

		 ifconfig_em0_alias0="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_em0_alias1="inet 127.0.0.254 netmask 0xffffffff"

		 It also possible to configure multiple IP addresses  in  Class-
		 less  Inter-Domain  Routing (CIDR) address notation, whose each
		 address component can be a range like inet  192.0.2.5-23/24  or
		 inet6	2001:db8:1-f::1/64.   This  notation  allows address and
		 prefix length part only, not the other address modifiers.  Note
		 that the maximum number of the generated addresses from a range
		 specification is limited  to  an  integer  value  specified  in
		 netif_ipexpand_max  in  rc.conf  because a small typo can unex-
		 pectedly generate a large number  of  addresses.   The  default
		 value	is  2048.   It	can be increased by adding the following
		 line into rc.conf:

		 netif_ipexpand_max="4096"

		 In the case of 192.0.2.5-23/24, the address 192.0.2.5	will  be
		 configured  with the netmask /24 and the addresses 192.0.2.6 to
		 192.0.2.23 with the non-conflicting netmask /32 as explained in
		 the ifconfig(8) alias section.  Note that this special  netmask
		 handling  is  only for inet, not for the other address families
		 such as inet6.

		 With the interface in question being em0, an example could look
		 like:

		 ifconfig_em0_alias2="inet 192.0.2.129/27"
		 ifconfig_em0_alias3="inet 192.0.2.1-5/28"

		 and so on.

		 Note that deprecated ipv4_addrs_<interface> variable  was  sup-
		 ported     for     IPv4    CIDR    address    notation.     The
		 ifconfig_<interface>_alias<n>	variable  replaces  it,   though
		 ipv4_addrs_<interface> is still supported for backward compati-
		 bility.

		 For  each  ifconfig_<interface>_alias<n>  entry with an address
		 family keyword, its contents are passed to ifconfig(8).  Execu-
		 tion stops at the first unsuccessful access,  so  if  something
		 like this is present:

		 ifconfig_em0_alias0="inet 127.0.0.251 netmask 0xffffffff"
		 ifconfig_em0_alias1="inet 127.0.0.252 netmask 0xffffffff"
		 ifconfig_em0_alias2="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_em0_alias4="inet 127.0.0.254 netmask 0xffffffff"

		 Then note that alias4 would not be added since the search would
		 stop  with  the missing "alias3" entry.  Because of this diffi-
		 cult to manage behavior, there is  ifconfig_<interface>_aliases
		 variable,    which    has    the    same    functionality    as
		 ifconfig_<interface>_alias<n> and can have all of entries in  a
		 variable like the following:

		 ifconfig_em0_aliases="\
			 inet 127.0.0.251 netmask 0xffffffff \
			 inet 127.0.0.252 netmask 0xffffffff \
			 inet 127.0.0.253 netmask 0xffffffff \
			 inet 127.0.0.254 netmask 0xffffffff"

		 It also supports CIDR notation.

		 If  the  /etc/start_if.<interface>  file is present, it is read
		 and executed by the sh(1) interpreter	before	configuring  the
		 interface   as   specified   in  the  ifconfig_<interface>  and
		 ifconfig_<interface>_alias<n> variables.

		 If a vlans_<interface> variable is  set,  a  vlan(4)  interface
		 will  be created for each item in the list with the vlandev ar-
		 gument set to interface.  If a vlan interface's name is a  num-
		 ber,  then that number is used as the vlan tag and the new vlan
		 interface is named interface.tag.  Otherwise, the vlan tag must
		 be    specified    via    a	vlan	parameter     in     the
		 create_args_<interface> variable.

		 To  create a vlan device named em0.101 on em0 with the vlan tag
		 101 and the optional the IPv4 address 192.0.2.1/24:

		 vlans_em0="101"
		 ifconfig_em0_101="inet 192.0.2.1/24"

		 To create a vlan device named myvlan on em0 with the  vlan  tag
		 102:

		 vlans_em0="myvlan"
		 create_args_myvlan="vlan 102"

		 If  a	wlans_<interface>  variable is set, an wlan(4) interface
		 will be created for each item in the list with the wlandev  ar-
		 gument set to interface.  Further wlan cloning arguments may be
		 passed  to  the  ifconfig(8)  create  command	by  setting  the
		 create_args_<interface> variable.  One or more wlan(4)  devices
		 must  be  created  for each wireless devices as of FreeBSD 8.0.
		 Debugging flags for wlan(4) devices as set by wlandebug(8)  may
		 be  specified with an wlandebug_<interface> variable.	The con-
		 tents of this variable will be passed directly to wlandebug(8).

		 If the ifconfig_<interface> contains the keyword "NOAUTO"  then
		 the   interface   will   not	be  configured	at  boot  or  by
		 /etc/pccard_ether when network_interfaces is set to "AUTO".

		 It is possible to bring up an interface  with	DHCP  by  adding
		 "DHCP"  to the ifconfig_<interface> variable.	For instance, to
		 initialize the em0 device via DHCP, it is possible to use some-
		 thing like:

		 ifconfig_em0="DHCP"

		 If you want to configure your wireless interface with	wpa_sup-
		 plicant(8)  for  use with WPA, EAP/LEAP or WEP, you need to add
		 "WPA" to the ifconfig_<interface> variable.

		 On the other hand, if you want to configure your  wireless  in-
		 terface  with	hostapd(8),  you  need	to  add  "HOSTAP" to the
		 ifconfig_<interface> variable.  hostapd(8) will  use  the  set-
		 tings from /etc/hostapd-<interface>.conf

		 Finally,  you	can add ifconfig(8) options in this variable, in
		 addition to the /etc/start_if.<interface> file.  For  instance,
		 to  configure an ath(4) wireless device in station mode with an
		 address obtained via DHCP, using WPA authentication and 802.11b
		 mode, it is possible to use something like:

		 wlans_ath0="wlan0"
		 ifconfig_wlan0="DHCP WPA mode 11b"

		 In addition to the ifconfig_<interface> form, a fallback  vari-
		 able  ifconfig_DEFAULT  may be configured.  It will be used for
		 all interfaces with no ifconfig_<interface> variable.	This  is
		 intended  to  replace	the  no longer supported pccard_ifconfig
		 variable.

		 It is also possible to rename an interface by doing:

		 ifconfig_em0_name="net0"
		 ifconfig_net0="inet 192.0.2.1 netmask 0xffffff00"

     ipv6_enable
		 (bool)     This     variable	   is	   deprecated.	     Use
		 ifconfig_<interface>_ipv6  and  ipv6_activate_all_interfaces if
		 necessary.

		 If the variable is "YES", "inet6 accept_rtadv" is added to  all
		 of	     ifconfig_<interface>_ipv6		and	     the
		 ipv6_activate_all_interfaces is defined as "YES".

     ipv6_prefer
		 (bool) This variable is deprecated.  Use ip6addrctl_policy  in-
		 stead.

		 If  the variable is "YES", the default address selection policy
		 table set by ip6addrctl(8) will be IPv6-preferred.

		 If the variable is "NO", the default address  selection  policy
		 table set by ip6addrctl(8) will be IPv4-preferred.

     ipv6_activate_all_interfaces
		 (bool)  This controls initial configuration on IPv6-capable in-
		 terfaces with no corresponding ifconfig_<interface>_ipv6  vari-
		 able.	 Note  that it is not always necessary to set this vari-
		 able to "YES" to use IPv6 functionality on  FreeBSD.	In  most
		 cases,  just  configuring  ifconfig_<interface>_ipv6  variables
		 works.

		 If the variable is "NO", all interfaces which	do  not  have  a
		 corresponding ifconfig_<interface>_ipv6 variable will be marked
		 as "IFDISABLED" at creation.  This means that all of IPv6 func-
		 tionality on that interface is completely disabled to enforce a
		 security  policy.   If  the  variable is set to "YES", the flag
		 will be cleared on all of the interfaces.

		 In most cases, just defining an  ifconfig_<interface>_ipv6  for
		 an IPv6-capable interface should be sufficient.  However, if an
		 interface  is	added  dynamically  (by some tunneling protocols
		 such as PPP, for example), it is often difficult to define  the
		 variable   in	 advance.   In	such  a  case,	configuring  the
		 "IFDISABLED" flag can be disabled by setting this  variable  to
		 "YES".

		 For  more  details of the "IFDISABLED" flag and keywords "inet6
		 ifdisabled", see ifconfig(8).

		 Default is "NO".

     ipv6_privacy
		 (bool) If the variable is "YES" privacy addresses will be  gen-
		 erated for each IPv6 interface as described in RFC 4941.

     ipv6_network_interfaces
		 (str)	This is the IPv6 equivalent of network_interfaces.  Nor-
		 mally manual configuration of this variable is not needed.

     ipv6_cpe_wanif
		 (str) If the variable is set to an interface name,  the  ifcon-
		 fig(8)  options  "inet6 -no_radr accept_rtadv" will be added to
		 the  specified  interface   automatically   before   evaluating
		 ifconfig_<interface>_ipv6,    and   two   sysctl(8)   variables
		 net.inet6.ip6.rfc6204w3 and net.inet6.ip6.no_radr will  be  set
		 to 1.

		 This  means  the  specified interface will accept ICMPv6 Router
		 Advertisement messages on that  link  and  add  the  discovered
		 routers  into	the Default Router List.  While the other inter-
		 faces can still accept RA messages if the "inet6  accept_rtadv"
		 option is specified, adding routes into the Default Router List
		 will be disabled by "inet6 no_radr" option by default.  See if-
		 config(8) for more details.

		 Note that ICMPv6 Router Advertisement messages will be accepted
		 even  when  net.inet6.ip6.forwarding is 1 (packet forwarding is
		 enabled) when net.inet6.ip6.rfc6204w3 is set to 1.

		 Default is "NO".

     ifconfig_<interface>_descr
		 (str) This assigns arbitrary description to an interface.   The
		 sysctl(8)  variable net.ifdescr_maxlen limits its length.  This
		 static setting may be overridden by commands started  with  dy-
		 namic interface configuration utilities like dhclient(8) hooks.
		 The description can be seen with ifconfig(8) command and it may
		 be exported with bsnmpd(1) daemon using its MIB-2 module.

     ifconfig_<interface>_ipv6
		 (str)	IPv6  functionality on an interface should be configured
		 by ifconfig_<interface>_ipv6, instead of setting ifconfig para-
		 meters in ifconfig_<interface>.  If this variable is empty, all
		 of IPv6 configurations on  the  specified  interface  by  other
		 variables such as ipv6_prefix_<interface> will be ignored.

		 Aliases  should  be  set  by ifconfig_<interface>_alias<n> with
		 "inet6" keyword.  For example:

		 ifconfig_em0_ipv6="inet6 2001:db8:1::1 prefixlen 64"
		 ifconfig_em0_alias0="inet6 2001:db8:2::1 prefixlen 64"

		 Interfaces  that  have  an  "inet6  accept_rtadv"  keyword   in
		 ifconfig_<interface>_ipv6 setting will be automatically config-
		 ured  by  SLAAC (StateLess Address AutoConfiguration) described
		 in RFC 4862.

		 Note that a link-local address will be automatically configured
		 in addition to the configured	global-scope  addresses  because
		 the  IPv6  specifications require it on each link.  The address
		 is calculated from the MAC address by using  an  algorithm  de-
		 fined in RFC 4862, Section 5.3.

		 If  only  a  link-local address is needed on the interface, the
		 following configuration can be used:

		 ifconfig_em0_ipv6="inet6 auto_linklocal"

		 A link-local address can also be configured manually.	This  is
		 useful for the default router address of an IPv6 router so that
		 it does not change when the network interface card is replaced.
		 For example:

		 ifconfig_em0_ipv6="inet6 fe80::1 prefixlen 64"

     ipv6_prefix_<interface>
		 (str)	  If	one    or   more   prefixes   are   defined   in
		 ipv6_prefix_<interface> addresses based on each prefix and  the
		 EUI-64  interface  index  will be configured on that interface.
		 Note	that   this    variable    will    be	 ignored    when
		 ifconfig_<interface>_ipv6 is empty.

		 For example, the following configuration

		 ipv6_prefix_em0="2001:db8:1:0 2001:db8:2:0"

		 is equivalent to the following:

		 ifconfig_em0_alias0="inet6 2001:db8:1:: eui64 prefixlen 64"
		 ifconfig_em0_alias1="inet6 2001:db8:1:: prefixlen 64 anycast"
		 ifconfig_em0_alias2="inet6 2001:db8:2:: eui64 prefixlen 64"
		 ifconfig_em0_alias3="inet6 2001:db8:2:: prefixlen 64 anycast"

		 These	Subnet-Router  anycast addresses will be added only when
		 ipv6_gateway_enable is YES.

     ipv6_default_interface
		 (str) If not set to "NO", this is the default output  interface
		 for  scoped  addresses.   This works only with ipv6_gateway_en-
		 able="NO".

     ip6addrctl_enable
		 (bool) This variable is to enable configuring	default  address
		 selection  policy table (RFC 3484).  The table can be specified
		 in another variable ip6addrctl_policy.   For  ip6addrctl_policy
		 the   following   keywords  can  be  specified:  "ipv4_prefer",
		 "ipv6_prefer", or "AUTO".

		 If "ipv4_prefer" or "ipv6_prefer" is  specified,  ip6addrctl(8)
		 installs  a  pre-defined policy table described in Section 10.3
		 (IPv4-preferred) or 2.1 (IPv6-preferred) of RFC 3484.

		 If  "AUTO"  is  specified,  it  attempts   to	 read	a   file
		 /etc/ip6addrctl.conf  first.	If  this  file	is found, ip6ad-
		 drctl(8) reads and installs it.  If not found, a policy is  au-
		 tomatically set according to ipv6_activate_all_interfaces vari-
		 able; if the variable is set to "YES" the IPv6-preferred one is
		 used.	Otherwise IPv4-preferred.

		 The  default  value  of ip6addrctl_enable and ip6addrctl_policy
		 are "YES" and "AUTO", respectively.

     cloned_interfaces
		 (str) Set to the list of clonable network interfaces to  create
		 on  this  host.  Further cloning arguments may be passed to the
		 ifconfig(8) create command for each interface	by  setting  the
		 create_args_<interface>  variable.   If  an  interface  name is
		 specified with ":sticky" keyword, the interface will not be de-
		 stroyed even when rc.d/netif script is invoked with "stop"  ar-
		 gument.   This is useful when reconfiguring the interface with-
		 out destroying it.  Entries in cloned_interfaces are  automati-
		 cally appended to network_interfaces for configuration.

     cloned_interfaces_sticky
		 (bool)  This  variable  is  to globally enable functionality of
		 ":sticky" keyword in cloned_interfaces for all interfaces.  The
		 default value is "NO".  Even if this variable is  specified  to
		 "YES",  ":nosticky"  keyword  can be used to override it on per
		 interface basis.

     gif_interfaces
		 Set to the list of gif(4) tunnel  interfaces  to  configure  on
		 this  host.  A gifconfig_<interface> variable is assumed to ex-
		 ist for each value of interface.  The value of this variable is
		 used to configure the link layer of the tunnel using the tunnel
		 option to ifconfig.  Additionally,  this  option  ensures  that
		 each  listed  interface is created via the create option to if-
		 config before attempting to configure it.

		 For example, configure two gif interfaces with:

		 gif_interfaces="gif0 gif1"
		 gifconfig_gif0="100.64.0.1 100.64.0.2"
		 ifconfig_gif0="inet 10.0.0.1 10.0.0.2 netmask 255.255.255.252"
		 gifconfig_gif1="inet6 2a00::1 2a01::1"
		 ifconfig_gif1="inet 10.1.0.1 10.1.0.2 netmask 255.255.255.252"

     sppp_interfaces
		 (str) Set to the list of sppp(4)  interfaces  to  configure  on
		 this host.  A spppconfig_<interface> variable is assumed to ex-
		 ist for each value of interface.  Each interface should also be
		 configured by a general ifconfig_<interface> setting.	Refer to
		 spppcontrol(8) for more information about available options.

     ppp_enable  (bool) If set to "YES", run the ppp(8) daemon.

     ppp_profile
		 (str)	The  name  of the profile to use from /etc/ppp/ppp.conf.
		 Also used for per-profile overrides of  ppp_mode  and	ppp_nat,
		 and  ppp_<profile>_unit.  When the profile name contains any of
		 the characters ".-/+" they are translated to "_" for  the  pro-
		 poses of the override variable names.

     ppp_mode	 (str) Mode in which to run the ppp(8) daemon.

     ppp_<profile>_mode
		 (str)	Overrides  the	global	ppp_mode  for profile.	Accepted
		 modes are "auto", "ddial", "direct" and "dedicated".	See  the
		 manual for a full description.

     ppp_nat	 (bool)  If  set  to "YES", enables network address translation.
		 Used in conjunction with gateway_enable allows hosts on private
		 network addresses access to the Internet using this host  as  a
		 network address translating router.  Default is "YES".

     ppp_<profile>_nat
		 (str) Overrides the global ppp_nat for profile.

     ppp_<profile>_unit
		 (int) Set the unit number to be used for this profile.  See the
		 manual description of -unitN for details.

     ppp_user	 (str)	The  name  of  the  user  under  which	ppp(8) should be
		 started.  By default, ppp(8) is started as "root".

     rc_conf_files
		 (str) This option is used to specify a list of files that  will
		 override the settings in /etc/defaults/rc.conf.  The files will
		 be read in the order in which they are specified and should in-
		 clude	the full path to the file.  By default, the files speci-
		 fied are /etc/rc.conf and /etc/rc.conf.local

     zfs_enable  (bool) If set to "YES", /etc/rc.d/zfs will attempt to automati-
		 cally	mount  ZFS  file  systems  and	initialize  ZFS  volumes
		 (ZVOLs).

     gptboot_enable
		 (bool)  If set to "YES", /etc/rc.d/gptboot will log if the sys-
		 tem successfully (or not) booted from a  GPT  partition,  which
		 had the bootonce attribute set using gpart(8) utility.

     gbde_autoattach_all
		 (bool) If set to "YES", /etc/rc.d/gbde will attempt to automat-
		 ically initialize your .bde devices in /etc/fstab.

     gbde_devices
		 (str) List the devices that the script should try to attach, or
		 "AUTO".

     gbde_lockdir
		 (str)	The  directory	where the gbde(4) lockfiles are located.
		 The default lockfile directory is /etc.

		 The lockfile for each individual gbde(4) device can be overrid-
		 den by setting the variable gbde_lock_<device>, where device is
		 the encrypted device without the "/dev/" and ".bde" parts.

     gbde_attach_attempts
		 (int) Number of times to attempt attaching to a gbde(4) device,
		 i.e., how many times the user is  asked  for  the  pass-phrase.
		 Default is 3.

     geli_devices
		 (str)	List  of  devices to automatically attach on boot.  Note
		 that .eli devices from /etc/fstab are automatically appended to
		 this list.

     geli_groups
		 (str) List of groups containing devices to automatically attach
		 on boot with the same keyfiles and passphrase.   This	must  be
		 accompanied with a corresponding geli_<group>_devices variable.

     geli_tries  (int)	Number	of  times user is asked for the pass-phrase.  If
		 empty, it will be taken from kern.geom.eli.tries  sysctl  vari-
		 able.

     geli_default_flags
		 (str) Default flags to use by geli(8) when configuring disk en-
		 cryption.   Flags can be configured for every device separately
		 by defining the geli_<device>_flags  variable,  and  for  every
		 group separately by defining the geli_<group>_flags variable.

     geli_autodetach
		 (str)	Specifies if GELI devices should be marked for detach on
		 last close after file systems are mounted.  Default  is  "YES".
		 This can be changed for every device separately by defining the
		 geli_<device>_autodetach variable.

     root_rw_mount
		 (bool)  Set  to  "YES"  by default.  After the file systems are
		 checked at boot time, the root  file  system  is  remounted  as
		 read-write  if  this  is  set	to "YES".  Diskless systems that
		 mount their root file system from a read-only remote NFS  share
		 should set this to "NO" in their rc.conf.

     fsck_y_enable
		 (bool) If set to "YES", fsck(8) will be run with the -y flag if
		 the initial preen of the file systems fails.

     background_fsck
		 (bool)  If  set  to  "NO",  the  system will not attempt to run
		 fsck(8) in the background where possible.

     background_fsck_delay
		 (int) The amount of time in seconds to sleep before starting  a
		 background  fsck(8).	It  defaults  to  sixty seconds to allow
		 large applications such as the X server to  start  before  disk
		 I/O  bandwidth is monopolized by fsck(8).  If set to a negative
		 number, the background file system check will be delayed indef-
		 initely to allow the administrator to run it at a  more  conve-
		 nient time.  For example it may be run from cron(8) by adding a
		 line like

		       0 4 * * * root /etc/rc.d/bgfsck forcestart

		 to /etc/crontab.

     netfs_types
		 (str)	List  of file system types that are network-based.  This
		 list should generally	not  be  modified  by  end  users.   Use
		 extra_netfs_types instead.

     extra_netfs_types
		 (str)	If  set to something other than "NO" (the default), this
		 variable extends the list of file system types for which  auto-
		 matic	mounting at startup by rc(8) should be delayed until the
		 network is initialized.  It should contain  a	whitespace-sepa-
		 rated	list  of network file system descriptor pairs, each con-
		 sisting of a file system type as passed to mount(8) and  a  hu-
		 man-readable,	one-word description, joined with a colon (`:').
		 Extending the default list in this way is only  necessary  when
		 third party file system types are used.

     syslogd_enable
		 (bool) If set to "YES", run the syslogd(8) daemon.

     syslogd_program
		 (str) Path to syslogd(8) (default /usr/sbin/syslogd).

     syslogd_flags
		 (str) If syslogd_enable is set to "YES", these are the flags to
		 pass to syslogd(8).

     inetd_enable
		 (bool) If set to "YES", run the inetd(8) daemon.

     inetd_program
		 (str) Path to inetd(8) (default /usr/sbin/inetd).

     inetd_flags
		 (str)	If  inetd_enable is set to "YES", these are the flags to
		 pass to inetd(8).

     hastd_enable
		 (bool) If set to "YES", run the hastd(8) daemon.

     hastd_program
		 (str) Path to hastd(8) (default /sbin/hastd).

     hastd_flags
		 (str) If hastd_enable is set to "YES", these are the  flags  to
		 pass to hastd(8).

     local_unbound_enable
		 (bool)  If  set  to "YES", run the unbound(8) daemon as a local
		 caching resolver.

     kdc_enable  (bool) Set to "YES" to start a Kerberos 5 authentication server
		 at boot time.

     kdc_program
		 (str) If kdc_enable is set to "YES" this is the  path	to  Ker-
		 beros 5 Authentication Server.

     kdc_flags	 (str)	Empty  by  default.   This  variable contains additional
		 flags to be passed to the Kerberos 5 authentication server.

     kadmind_enable
		 (bool) Set to "YES" to start kadmind(8), the Kerberos 5  Admin-
		 istration Daemon; set to "NO" on a slave server.

     kadmind_program

		 ing cut/paste selection on the console.

     moused_type
		 (str)	This is the protocol type of the mouse connected to this

		 "auto" to let the daemon detect it, or select one from the fol-
		 lowing list if the automatic detection fails.

		 If  the mouse is attached to the PS/2 mouse port, choose "auto"
		 or "ps/2", regardless of the brand  and  model  of  the  mouse.
		 Likewise,  if	the  mouse  is	attached  to the bus mouse port,
		 choose "auto" or "busmouse".  All other protocols are for  ser-
		 ial mice and will not work with the PS/2 and bus mice.  If this
		 is  a	USB  mouse,  "auto" is the only protocol type which will
		 work.

		 Even if the mouse is not in the above list, it may be	compati-
		 ble  with  one  in  the  list.   Refer  to  the manual page for
		 moused(8) for compatibility information.

		 It should also be noted that while this is enabled,  any  other
		 client  of  the  mouse  (such as an X server) should access the
		 mouse through the virtual mouse device, /dev/sysmouse, and con-
		 figure it as a "sysmouse" type mouse, since all mouse	data  is
		 converted to this single canonical format when using moused(8).
		 If  the  client  program  does not support the "sysmouse" type,
		 specify the "mousesystems" type.  It is  the  second  preferred
		 type.

     moused_port
		 (str) If moused_enable is set to "YES", this is the actual port

		 mon is started for a non-default port, the moused_XXX_flags set
		 of  options  has  precedence  over  and  replaces  the  default
		 moused_flags  (where  XXX  is the name of the non-default port,
		 i.e., ums0).  By setting moused_XXX_flags it is possible to set
		 up a different set of default	flags  for  each  moused(8)  in-
		 stance.   For	example,  you  can  use  "-3"  for  the  default
		 moused_flags to make your laptop's touchpad more comfortable to
		 use, but an empty set of  options  for  moused_ums0_flags  when
		 your usb(4) mouse has three or more buttons.

     mousechar_start
		 (int)	If set to "NO", the default mouse cursor character range
		 0xd0-0xd3 is used, otherwise the range start is  set  to  value

		 cupied in the language code table.

     allscreens_flags
		 (str) If set, vidcontrol(1) is run with these options for  each
		 of  the  virtual  terminals (/dev/ttyv*).  For example, "-m on"

     allscreens_kbdflags
		 (str)	If set, kbdcontrol(1) is run with these options for each
		 of the virtual terminals (/dev/ttyv*).  For example,  "-h  200"

		 was able to be set by jail_vjail_hostname.  These per-jail con-
		 figuration variables are now obsolete in favor of jail(8)  con-
		 figuration  file.   For  backward  compatibility, when per-jail

		 script out of their corresponding rc.conf variables.  In  addi-
		 tion  to  them,  parameters  in jail_<jname>_parameters will be
		 added to the configuration file.  They  must  be  a  semi-colon

		 for  the  execution  of  rc.shutdown.	 This  is configured via
		 sysctl(8) variable kern.init_shutdown_timeout and  defaults  to
		 120  seconds.	 Setting the value of rcshutdown_timeout to more

		 (bool)  If  set  to  "YES", delays the start of network-reliant
		 services until netwait_if is up and ICMP packets to a	destina-
		 tion defined in netwait_ip are flowing.  Link state is examined
		 first,  followed  by  "pinging" an IP address to verify network
