SYSINSTALL(8)           FreeBSD System Manager's Manual          SYSINSTALL(8)

NAME
     sysinstall -- system installation and configuration tool

SYNOPSIS
     sysinstall [var=value] [function] [...]

DESCRIPTION
     sysinstall is a utility for installing and configuring FreeBSD systems.
     It is the first utility invoked by the FreeBSD installation boot floppy
     and is also copied into /stand/sysinstall on newly installed FreeBSD sys-
     tems for use in later configuring the system.

     The sysinstall program is generally invoked without arguments for the
     default 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
     sysinstall is essentially nothing more than a monolithic C program 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
     installation boot procedure.  It assumes very little in the way of addi-
     tional utility support and performs most file system operations by call-
     ing the relevant syscalls (such as mount(2)) directly.

     sysinstall currently uses the dialog(3) library to do user interaction
     with simple ANSI line graphics, color support for which is enabled by
     either running on a syscons VTY or some other color-capable terminal emu-
     lator (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 eventu-
     ally be replaced.

RUNNING SCRIPTS
     sysinstall may be either driven interactively through its various inter-
     nal 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 envi-
             ronment (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
             single prototype install for multiple machines with largely iden-
             tical 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 con-
             fig 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
             explicit 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 edi-
             tor, 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
     comment for documentation purposes (ignored by sysinstall).  Each direc-
     tive must be by itself on a single line, functions taking their arguments
     by examining 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 vari-
     ables will be noted in the following table:

             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 main-
                    tain a proper partition table, existing to use an existing
                    FreeBSD partition (first found), exclusive to use the disk
                    in ``dangerously dedicated'' mode or, finally, somenumber
                    to allocate 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 "stan-
                    dard" 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
             explicit call to diskPartitionWrite being required for that to
             happen.

     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
             perform the installation interactively at least once and take
             careful notes as to what the slice names will be, then and only
             then hardwiring them into the script.

             For example, let's say you have a SCSI disk on which you've cre-
             ated a new FreeBSD partition in slice 2 (your DOS partition
             residing in slice 1).  The slice name would be da0s2 for the
             whole FreeBSD partition (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 involve 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 argu-
                    ment following the mount point, if non-zero, means to set
                    the soft updates flag).

             One can also use the diskLabelEditor for mounting or erasing
             existing partitions as well as creating new ones.  Using the pre-
             vious example again, let's say that we also wanted to mount our
             DOS partition 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 parti-
             tion 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
             described above.

             Note:  No file system data is actually written to disk until an
             explicit 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: None

     distReset
             Resets all selected distributions to the empty set (no distribu-
             tions selected).

             Variables: None

     distSetCustom
             Allows the selection of a custom distribution set (e.g. not just
             on of the existing "canned" sets) with no user interaction.

             Variables:

             dists   List of distributions to load.  Possible distribution
                     values are:

                     bin       The base binary distribution.
