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, sysinstall(8).

     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/rc.conf.local is used  to
     override	settings  in  /etc/rc.conf  for  historical  reasons.	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.

     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).

     swapfile	 (str) If set to "NO", no swapfile is installed,  otherwise  the
		 value	is  used as the full pathname to a file to use for addi-
		 tional swap space.

     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.

     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.  If this value remains unset
		 when the system is done booting your console login will display
		 the default hostname of "Amnesiac."

     ipv6_enable
		 (bool) Enable support for IPv6 networking.  Note that this  re-
		 quires that the kernel has been compiled with options INET6.

     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
		 (is   currently   in  beta  test.   Set  to  "bool")  to  start
		 dhclient(8) only in response to interface events and  not  syn-
		 chronously  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".

     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.

     ipv6_firewall_enable
		 (bool) The IPv6 equivalent of firewall_enable.  Set to "YES" to
		 load  IPv6  firewall  rules  at startup.  If the kernel was not
		 built with options IPV6FIREWALL, the ipfw.ko kernel module will
		 be loaded.

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

     ipv6_firewall_script
		 (str) The IPv6 equivalent of firewall_script.

     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.

     ipv6_firewall_type
		 (str) The IPv6 equivalent of firewall_type.

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

     ipv6_firewall_quiet
		 (bool) The IPv6 equivalent of firewall_quiet.

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

     ipv6_firewall_logging
		 (bool) The IPv6 equivalent of firewall_logging.

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

     ipv6_firewall_flags
		 (str) The IPv6 equivalent of firewall_flags.

     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" enables kernel NAT.  firewall_enable must also be 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.

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

     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.

     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.

     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 "NO" by default.  Setting to "YES" will cause the
		 kernel  to  ignore 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.

		 One   can  configure  more  than  one	IPv4  address  with  the
		 ipv4_addrs_<interface> variable.  One or more IP addresses must
		 be provided in Classless Inter-Domain	Routing  (CIDR)  address
		 notation,  whose last byte can be a range like 192.0.2.5-23/24.
		 In this case 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.   With  the interface in question being ed0, an
		 example could look like:

		 ipv4_addrs_ed0="192.0.2.129/27 192.0.2.1-5/28"

		 It is also possible to add IP alias entries  using  ifconfig(8)
		 syntax.   Assuming  that  the interface in question was ed0, it
		 might look something like this:

		 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

		 And so on.  For each ifconfig_<interface>_alias<n>  entry  that
		 is  found,  its  contents are passed to ifconfig(8).  Execution
		 stops at the first unsuccessful access, so  if  something  like
		 this is present:

		 ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
		 ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
		 ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_ed0_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.	Due to this difficult to
		 manage behavior, the ifconfig_<interface>_alias<n> form is dep-
		 recated.

		 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:

		 vlans_em0="101"

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

		 vlans_em0="myvlan"
		 create_args_myvlan="vlan 102"

		 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 ed0 device via DHCP, it is possible to use some-
		 thing like:

		 ifconfig_ed0="DHCP"

		 Also,	if your interface needs WPA authentication, it is possi-
		 ble to add "WPA" to the ifconfig_<interface> variable.

		 Finally, you can add ifconfig(8) options in this  variable,  in
		 addition  to the /etc/start_if.<interface> file.  For instance,
		 to initialize the wi0 device via DHCP, using WPA authentication
		 and 802.11b mode, it is possible to use something like:

		 ifconfig_wi0="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_ed0_name="net0"
		 ifconfig_net0="inet 192.0.2.1 netmask 0xffffff00"

     ipv6_network_interfaces
		 (str) This is the IPv6 equivalent of  network_interfaces.   In-
		 stead of setting the ifconfig variables as ifconfig_<interface>
		 they  should  be  set	as  ipv6_ifconfig_<interface>.	 Aliases
		 should   be	set    as    ipv6_ifconfig_<interface>_alias<n>.
		 ipv6_prefix_<interface> does something.  Interfaces that do not
		 have  a  ipv6_ifconfig_<interface> setting will be auto config-
		 ured by rtsol(8) if the ipv6_gateway_enable  is  set  to  "NO".
		 Note  that  the  IPv6	networking  code  does	not  support the
		 /etc/start_if.<interface> files.

		 are automatically appended to network_interfaces for configura-
		 tion.

     fec_interfaces
		 (str) Set to the list of ng_fec(4) Fast EtherChannel interfaces
		 to configure on this host.  A fecconfig_<interface> variable is
		 assumed  to  exist  for  each value of interface.  The value of
		 this variable is used to configure link  aggregated  interfaces
		 according  to	the  syntax of the NGM_FEC_ADD_IFACE to ngctl(8)
		 msg.  Additionally, this option ensures that each listed inter-
		 face is created via the mkpeer command to ngctl(8)  before  at-
		 tempting to configure it.  For example:

		 fec_interfaces="fec0"
		 fecconfig_fec0="em0 em1"
		 ifconfig_fec0="DHCP"

     gif_interfaces
		 (str)	Set to the list of gif(4) tunnel interfaces to configure
		 on this host.	A gifconfig_<interface> variable is  assumed  to
		 exist	for each value of interface.  The value of this variable
		 is used to configure the link layer of the tunnel according  to
		 the  syntax of the tunnel option to ifconfig(8).  Additionally,
		 this option ensures that each listed interface is  created  via
		 the create option to ifconfig(8) before attempting to configure
		 it.

     sppp_interfaces
		 (str)	Set  to  the  list of sppp(4) interfaces to configure on
		 this host.  A spppconfig_<interface> variable is assumed to ex-

		 (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

		 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

		 rated	list  of network file system descriptor pairs, each con-
		 sisting of a file system type as passed to mount(8) and  a  hu-

		 line	is   not   automatically   treated  as	enabled  by  the
		 /etc/rc.d/moused script.  Having this variable set to "YES" al-
		 lows a usb(4) mouse, for example, to be enabled as soon  as  it
		 is plugged in.

     moused_enable

		 ing cut/paste selection on the console.

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

		 "YES".  The moused(8) daemon is able to detect the  appropriate
		 mouse	type  automatically in many cases.  Set this variable to
		 "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.

		 microsoft	 Microsoft mouse (serial)

		 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
		 the mouse is on.  It might be	/dev/cuad0  for  a  COM1  serial

		 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"

		 Otherwise, the value of this variable is passed as the argument
		 to dumpon(8).	To disable crash dumps,  set  this  variable  to
		 "NO".

     dumpdir	 (str) When the system reboots after a crash and a crash dump is
		 found	 on  the  device  specified  by  the  dumpdev  variable,
		 savecore(8) will save that crash dump and a copy of the  kernel
