SYSINSTALL(8) System Manager's Manual SYSINSTALL(8) NAME sysinstall -- system installation and configuration tool SYNOPSIS sysinstall [var=value] [function] [...] DESCRIPTION The sysinstall utility is used for installing and configuring FreeBSD sys- tems. It is the first utility invoked by the FreeBSD installation boot floppy and is also copied into /stand/sysinstall on newly installed FreeBSD systems for use in later configuring the system. The sysinstall utility is generally invoked without arguments for the de- fault behavior, where the main installation/configuration menu is pre- sented. On those occasions where it is deemed necessary to invoke a subsystem of sysinstall directly, however, it is also possible to do so by naming the appropriate function entry points on the command line. Since this action is essentially identical to running an installation script, each command- line argument corresponding to a line of script, the reader is encouraged to read the section on scripting for more information on this feature. NOTES The sysinstall utility is essentially nothing more than a monolithic C pro- gram with the ability to write MBRs and disk labels (through the services of the libdisk(3) library) and install distributions or packages onto new and existing FreeBSD systems. It also contains some extra intelligence for running as a replacement for init(8) when it's invoked by the FreeBSD in- stallation boot procedure. It assumes very little in the way of additional utility support and performs most file system operations by calling the relevant syscalls (such as mount(2)) directly. The sysinstall utility currently uses the dialog(3) library to do user in- teraction with simple ANSI line graphics, color support for which is en- abled by either running on a syscons VTY or some other color-capable termi- nal emulator (newer versions of xterm will support color when using the "xterm-color" termcap entry). This product is currently at the end of its life cycle and will eventually be replaced. RUNNING SCRIPTS The sysinstall utility may be either driven interactively through its vari- ous internal menus or run in batch mode, driven by an external script. Such a script may be loaded and executed in one of 3 ways: LOAD_CONFIG_FILE If sysinstall is compiled with LOAD_CONFIG_FILE set in the environ- ment (or in the Makefile) to some value, then that value will be used as the filename to automatically look for and load when sysinstall starts up and with no user interaction required. This option is aimed primarily at large sites who wish to create a sin- gle prototype install for multiple machines with largely identical configurations and/or installation options. MAIN MENU If sysinstall is run interactively, that is to say in the default manner, it will bring up a main menu which contains a "load config file" option. Selecting this option will prompt for the name of a script file which it then will attempt to load from a DOS or UFS formatted floppy. COMMAND LINE Each command line argument is treated as a script directive when sysinstall is run in multi-user mode. Execution ends either by ex- plicit request (e.g. calling the shutdown directive), upon reaching the end of the argument list or on error. For example: /stand/sysinstall _ftpPath=ftp://ziggy/pub/ mediaSetFTP configPackages Would initialize sysinstall for FTP installation media (using the server `ziggy') and then bring up the package installation editor, exiting when finished. SCRIPT SYNTAX A script is a list of one or more directives, each directive taking the form of: var=value function or #somecomment Where var=value is the assignment of some internal sysinstall variable, e.g. "ftpPass=FuNkYChiKn", and function is the name of an internal sysinstall function, e.g. "mediaSetFTP", and #comment is a single-line com- ment for documentation purposes (ignored by sysinstall). Each directive must be by itself on a single line, functions taking their arguments by ex- amining known variable names. This requires that you be sure to assign the relevant variables before calling a function which requires them. The noError variable can be assigned before each directive: this will cause any error detected while processing the directive itself to be ignored. The value of noError will automatically reset to the default "unassigned" every time a directive is processed. When and where a function depends on the settings of one or more variables will be noted in the following table: Function Glossary: configAnonFTP Invoke the Anonymous FTP configuration menu. Variables: None configRouter Select which routing daemon you wish to use, potentially loading any required 3rd-party routing daemons as necessary. Variables: router can be set to the name of the desired routing daemon, e.g. "routed" or "gated", otherwise it is prompted for. configNFSServer Configure host as an NFS server. Variables: None configNTP Configure host as a user of the Network Time Protocol. Variables: ntpdate_flags The flags to ntpdate(8), that is to say the name of the server to sync from. configPCNFSD Configure host to support PC NFS. Variables: pcnfsd_pkg The name of the PCNFSD package to load if necessary (de- faults to hard coded version). configPackages Bring up the interactive package management menu. Variables: None configUsers Add users and/or groups to the system. Variables: None configXSetup Configure the X display subsystem. Variables: None configXDesktop Configure the X desktop. Variables: None diskPartitionEditor Invokes the disk partition (MBR) editor. Variables: geometry The disk geometry, as a cyls/heads/sectors formatted string. Default: no change to geometry. partition Set to disk partitioning type or size, its value being free in order to use only remaining free space for FreeBSD, all to use the entire disk for FreeBSD but maintain a proper partition table, existing to use an existing FreeBSD parti- tion (first found), exclusive to use the disk in "dangerously dedicated" mode or, finally, somenumber to al- locate somenumber blocks of available free space to a new FreeBSD partition. Default: Interactive mode. bootManager is set to one of boot to signify the installation of a boot manager, standard to signify installation of a "standard" non-boot MGR DOS MBR or none to indicate that no change to the boot manager is desired. Default: none. diskInteractive If set, bring up the interactive disk partition editor. Note: Nothing is actually written to disk by this function, a ex- plicit call to diskPartitionWrite being required for that to hap- pen. diskPartitionWrite Causes any pending MBR changes (typically from the diskPartitionEditor function) to be written out. Variables: None diskLabelEditor Invokes the disk label editor. This is a bit trickier from a script since you need to essentially label everything inside each FreeBSD (type 0xA5) partition created by the diskPartitionEditor function, and that requires knowing a few rules about how things are laid out. When creating a script to automatically allocate disk space and partition it up, it is suggested that you first per- form the installation interactively at least once and take careful notes as to what the slice names will be, then and only then hard- wiring them into the script. For example, let's say you have a SCSI disk on which you've created a new FreeBSD partition in slice 2 (your DOS partition residing in slice 1). The slice name would be da0s2 for the whole FreeBSD par- tition (da0s1 being your DOS primary partition). Now let's further assume that you have 500MB in this partition and you want to sub- partition that space into root, swap, var and usr file systems for FreeBSD. Your invocation of the diskLabelEditor function might in- volve setting the following variables: da0s2-1=ufs 40960 / A 20MB root file system (all sizes are in 512 byte blocks). da0s2-2=swap 131072 / A 64MB swap partition. da0s2-3=ufs 204800 /var A 100MB /var file system. da0s2-4=ufs 0 /usr 1 With the balance of free space (around 316MB) going to the /usr file system and with soft-updates enabled (the argument following the mount point, if non-zero, means to set the soft updates flag). One can also use the diskLabelEditor for mounting or erasing exist- ing partitions as well as creating new ones. Using the previous example again, let's say that we also wanted to mount our DOS par- tition and make sure that an /etc/fstab entry is created for it in the new installation. Before calling the diskLabelEditor function, we simply add an additional line: da0s1=/dos_c N before the call. This tells the label editor that you want to mount the first slice on /dos_c and not to attempt to newfs it (not that sysinstall would attempt this for a DOS partition in any case, but it could just as easily be an existing UFS partition being named here and the 2nd field is non-optional). You can also set the diskInteractive variable to request that the disk label editor use an interactive dialog to partition the disk instead of using variables to explicitly layout the disk as de- scribed above. Note: No file system data is actually written to disk until an ex- plicit call to diskLabelCommit is made. diskLabelCommit Writes out all pending disklabel information and creates and/or mounts any file systems which have requests pending from the diskLabelEditor function.

Variables: Same as for mediaSetFTP except that _ftpPath is not used. DISTRIBUTION MEDIA The following files can be used to affect the operation of sysinstall when used during initial system installation. cdrom.inf A text file of properties, listed one per line, that de- scribe the contents of the media in use. The syntax for each line is simply "property = value". Currently, only the following properties are recognized. CD_VERSION This property should be set to the FreeBSD version on the current media volume. For example, "CD_VERSION = 4.6". CD_MACHINE_ARCH This property should be set to the archi- tecture of the contents on this volume. This property is normally only used with FreeBSD products that contain CDs for dif- ferent architectures, to provide better error messages if users try to install Al- pha packages on an i386 machine. For ex- ample, "CD_MACHINE_ARCH = alpha". VOLUME In a multi-volume collection (such as the FreeBSD 4-CD set), the ports/INDEX file on each disc should contain the full package index for the set. The last field of the INDEX file denotes which volume the pack- age appears on, and the VOLUME property here defines the volume ID of the current disc. packages/INDEX The package index file. Each package is listed on a sepa- rate line with additional meta-data such as the required dependencies. This index is generated by "make index" from the ports(7) collection. When multi-volume support is en- abled, an additional field should be added to each line in- dicating which media volume contains the given package. For information about building a full release of FreeBSD, please see re- lease(7). FILES This utility may edit the contents of /etc/rc.conf, /etc/hosts, and /etc/resolv.conf as necessary to reflect changes in the network configura- tion. SEE ALSO If you have a reasonably complete source tree online, take a look at /usr/src/usr.sbin/sysinstall/install.cfg for a sample installation script. BUGS This utility is a prototype which lasted several years past its expiration date and is greatly in need of death. AUTHORS Jordan K.
