.Sh NAME
|
|
.Nm bsdinstall
|
|
.Nd system installer
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Ar options
|
|
.Op Ar target
|
|
.Op Ar ...
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is used for installation of new systems, both for system setup from
|
|
installation media (e.g. CD-ROMs) and for use on live systems to prepare
|
|
VM images and jails.
|
|
.Pp
|
|
Much like
|
|
.Xr make 1 , Nm
|
|
takes a target and possible parameters of the target as arguments. If
|
|
invoked with no arguments, it will invoke the
|
|
.Cm auto
|
|
target, which provides a standard interactive installation, invoking the
|
|
others in sequence. To perform a scripted installation, these subtargets
|
|
can be invoked separately by an installation script.
|
|
.Sh OPTIONS
|
|
.Nm
|
|
supports the following options, global to all targets:
|
|
.Bl -tag -width indent+
|
|
.It Fl D Ar file
|
|
Provide a path for the installation log file
|
|
.Pq overrides Ev BSDINSTALL_LOG .
|
|
See
|
|
.Sx ENVIRONMENT VARIABLES
|
|
for more information on
|
|
.Ev BSDINSTALL_LOG .
|
|
.El
|
|
.Sh TARGETS
|
|
Most of the following targets are only useful for scripting the installer.
|
|
For interactive use, most users will be interested only in the
|
|
.Cm auto ,
|
|
.Cm jail ,
|
|
and
|
|
.Cm script
|
|
targets.
|
|
.Bl -tag -width ".Cm jail Ar destination"
|
|
.It Cm auto
|
|
Run the standard interactive installation, including disk partitioning.
|
|
.It Cm jail Ar destination
|
|
Sets up a new chroot system at
|
|
.Pa destination ,
|
|
suitable for use with
|
|
.Xr jail 8 .
|
|
Behavior is generally similar to
|
|
.Cm auto ,
|
|
except that disk partitioning and network setup are skipped and a kernel is
|
|
not installed into the new system.
|
|
.It Cm script Ar script
|
|
Runs the installation script at
|
|
.Pa script .
|
|
See
|
|
.Sx SCRIPTING
|
|
for more information on this target.
|
|
.It Cm keymap
|
|
If the current controlling TTY is a
|
|
.Xr syscons 4
|
|
or
|
|
.Xr vt 4
|
|
console, asks the user to set the current keymap, and saves the result to the
|
|
new system's
|
|
.Pa rc.conf .
|
|
.It Cm hostname
|
|
Prompts the user for a host name for the new system and saves the result to the
|
|
new system's
|
|
.Pa rc.conf .
|
|
If
|
|
.Ev BSDINSTALL_CONFIGCURRENT
|
|
is set, also sets the host name of the current system.
|
|
.It Cm netconfig
|
|
Interactively configures network interfaces (first invoking
|
|
.Cm wlanconfig
|
|
on wireless interfaces), saving the result to the new system's
|
|
.Pa rc.conf
|
|
and
|
|
.Pa resolv.conf .
|
|
If
|
|
.Ev BSDINSTALL_CONFIGCURRENT
|
|
is set, also configures the network interfaces of the current system to match.
|
|
.It Cm autopart
|
|
Provides the installer's interactive guided disk partitioner for single-disk
|
|
installations. Defaults to UFS.
|
|
.It Cm zfsboot
|
|
Provides an alternative ZFS-only automatic interactive disk partitioner.
|
|
Creates a single
|
|
.Ic zpool
|
|
with separate datasets for
|
|
.Pa /tmp ,
|
|
.Pa /usr ,
|
|
.Pa /usr/home ,
|
|
.Pa /usr/ports ,
|
|
.Pa /usr/src ,
|
|
and
|
|
.Pa /var .
|
|
Optionally can set up
|
|
.Xr geli 8
|
|
to encrypt the disk.
|
|
.It Cm partedit
|
|
Provides the installer's interactive manual disk partitioner with an interface
|
|
identical to
|
|
.Xr sade 8 .
|
|
Supports multiple disks as well as UFS, ZFS, and FAT file systems. ZFS
|
|
is set up with one pool and dataset per partition.
|
|
.It Cm scriptedpart Ar parameters
|
|
Sets up disks like
|
|
.Cm autopart
|
|
and
|
|
.Cm partedit ,
|
|
but non-interactively according to the disk setup specified in
|
|
.Ar parameters .
|
|
Each disk setup is specified by a three-part argument:
|
|
.Pp
|
|
.Ar disk
|
|
.Op Ar scheme
|
|
.Op Ar {partitions}
|
|
.Pp
|
|
Multiple disk setups are separated by semicolons. The
|
|
.Ar disk
|
|
argument specifies the disk on which to operate (which will be erased),
|
|
while the
|
|
.Ar scheme
|
|
argument specifies the
|
|
.Xr gpart 8
|
|
partition scheme to apply to the disk. If
|
|
.Ar scheme
|
|
is unspecified,
|
|
.Cm scriptedpart
|
|
will apply the default bootable scheme on your platform.
|
|
The
|
|
.Ar partitions
|
|
argument is also optional and specifies how to partition
|
|
.Ar disk .
|
|
It consists of a comma-separated list of partitions to create enclosed in
|
|
curly braces. Each partition declaration takes the form
|
|
.Pp
|
|
.Ar size
|
|
.Ar type
|
|
.Op Ar mount point
|
|
.Pp
|
|
.Ar size
|
|
specifies the partition size to create in bytes (K, M, and G suffixes
|
|
can be appended to specify kilobytes, megabytes, and gigabytes respectively),
|
|
while the
|
|
.Em auto
|
|
keyword causes the partition to take all the remaining space on the disk. The
|
|
.Ar type
|
|
option chooses the
|
|
.Xr gpart 8
|
|
filesystem type (e.g. freebsd-ufs, freebsd-zfs, or freebsd-swap).
|
|
The optional
|
|
.Ar mount point
|
|
argument sets where the created partition is to be mounted in the installed
|
|
system. As an example, a typical invocation looks like:
|
|
.Pp
|
|
bsdinstall scriptedpart ada0 { 20G freebsd-ufs /, 4G freebsd-swap, 20G freebsd-ufs /var, auto freebsd-ufs /usr }
|
|
.Pp
|
|
A shorter invocation to use the default partitioning (as
|
|
.Cm autopart
|
|
would have used) on the same disk:
|
|
.Pp
|
|
bsdinstall scriptedpart ada0
|
|
.It Cm mount
|
|
Mounts the file systems previously configured by
|
|
.Cm autopart ,
|
|
.Cm partedit ,
|
|
or
|
|
.Cm scriptedpart
|
|
under
|
|
.Ev BSDINSTALL_CHROOT .
|
|
.It Cm distfetch
|
|
Fetches the distributions in
|
|
.Ev DISTRIBUTIONS
|
|
to
|
|
.Ev BSDINSTALL_DISTDIR
|
|
from
|
|
.Ev BSDINSTALL_DISTSITE .
|
|
.It Cm checksum
|
|
Verifies the checksums of the distributions listed in
|
|
.Ev DISTRIBUTIONS
|
|
against the distribution manifest.
|
|
.It Cm distextract
|
|
Extracts the distributions listed in
|
|
.Ev DISTRIBUTIONS
|
|
into
|
|
.Ev BSDINSTALL_CHROOT .
|
|
.It Cm rootpass
|
|
Interactively invokes
|
|
.Xr passwd 1
|
|
in the new system to set the root user's password.
|
|
.It Cm adduser
|
|
Interactively invokes
|
|
.Xr adduser 8
|
|
in the new system.
|
|
.It Cm time
|
|
Interactively sets the time, date, and time zone of the new system.
|
|
.It Cm services
|
|
Queries the user for the system daemons to begin at system startup,
|
|
writing the result into the new system's
|
|
.Pa rc.conf .
|
|
.It Cm entropy
|
|
Reads a small amount of data from
|
|
.Pa /dev/random
|
|
and stores it in a file in the new system's root directory.
|
|
.It Cm config
|
|
Installs the configuration files destined for the new system (e.g. rc.conf
|
|
fragments generated by
|
|
.Cm netconfig ,
|
|
etc.) onto the new system.
|
|
.El
|
|
.Sh ENVIRONMENT VARIABLES
|
|
The following environment variables control various aspects of the installation
|
|
process. Many are used internally during installation and have reasonable
|
|
default values for most installation scenarios. Others are set by various
|
|
interactive user prompts, and can be usefully overridden when making scripted
|
|
or customized installers.
|
|
.Bl -tag -width ".Ev BSDINSTALL_DISTSITE"
|
|
.It Ev DISTRIBUTIONS
|
|
The set of distributions to install (e.g. "base kernel ports"). Default: none
|
|
.It Ev BSDINSTALL_DISTDIR
|
|
The directory in which the distribution files can be found (or to which they
|
|
should be downloaded). Default:
|
|
.Pa /usr/freebsd-dist
|
|
.It Ev BSDINSTALL_DISTSITE
|
|
URL from which the distribution files should be downloaded if they are not
|
|
already present in the directory defined by
|
|
.Ev BSDINSTALL_DISTDIR .
|
|
This should be a full path to the files, including architecture and release
|
|
names. Most targets (e.g.
|
|
.Cm auto
|
|
and
|
|
.Cm jail )
|
|
that prompt for a
|
|
.Fx
|
|
mirror will skip that step if this variable is already defined in the
|
|
environment. Example:
|
|
.Pa ftp://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/powerpc64/9.1-RELEASE
|
|
.It Ev BSDINSTALL_CHROOT
|
|
The directory into which the distribution files should be unpacked and the
|
|
directory at which the root file system of the new system should be mounted.
|
|
Default:
|
|
.Pa /mnt
|
|
.It Ev BSDINSTALL_LOG
|
|
Path to a log file for the installation. Default:
|
|
.Pa /tmp/bsdinstall_log
|
|
.It Ev BSDINSTALL_TMPETC
|
|
Directory where files destined for the new system's
|
|
.Pa /etc
|
|
will be stored until the
|
|
.Cm config
|
|
target is executed. If this directory does not already exist, it will be
|
|
created. Default:
|
|
.Pa /tmp/bsdinstall_etc
|
|
.It Ev BSDINSTALL_TMPBOOT
|
|
Directory where files destined for the new system's
|
|
.Pa /boot
|
|
will be stored until the
|
|
.Cm config
|
|
target is executed. If this directory does not already exist, it will be
|
|
created. Default:
|
|
.Pa /tmp/bsdinstall_boot
|
|
.El
|
|
.Sh SCRIPTING
|
|
.Nm
|
|
scripts consist of two parts: a
|
|
.Em preamble
|
|
and a
|
|
.Em setup script .
|
|
The preamble sets up the options for the installation (how to partition the
|
|
disk[s], which distributions to install, etc.) and the optional second part is
|
|
a shell script run under
|
|
.Xr chroot 8
|
|
in the newly installed system before
|
|
.Nm
|
|
exits. The two parts are separated by the usual script header (#!), which
|
|
also sets the interpreter for the setup script.
|
|
.Pp
|
|
A typical bsdinstall script looks like this:
|
|
.Bd -literal -offset indent
|
|
PARTITIONS=ada0
|
|
DISTRIBUTIONS="kernel.txz base.txz"
|
|
|
|
#!/bin/sh
|
|
echo "ifconfig_em0=DHCP" >> /etc/rc.conf
|
|
echo "sshd_enable=YES" >> /etc/rc.conf
|
|
pkg install puppet
|
|
.Ed
|
|
.Pp
|
|
On
|
|
.Fx
|
|
release media, such a script placed at
|
|
.Pa /etc/installerconfig
|
|
will be run at boot time and the system will be rebooted automatically after
|
|
the installation has completed. This can be used for unattended network
|
|
installation of new systems; see
|
|
.Xr diskless 8
|
|
for details.
|
|
.Ss PREAMBLE
|
|
The preamble consists of installer settings. These control global installation
|
|
parameters (see
|
|
.Sx ENVIRONMENT VARIABLES )
|
|
as well as disk partitioning. The preamble is interpreted as a
|
|
.Xr sh 1
|
|
script run at the very beginning of the install. If more complicated behavior
|
|
than setting these variables is desired, arbitrary commands can be run here
|
|
to extend the installer. In addition to the variables in
|
|
.Sx ENVIRONMENT VARIABLES ,
|
|
in particular
|
|
.Ev DISTRIBUTIONS ,
|
|
the preamble can contain a variable
|
|
.Ev PARTITIONS
|
|
which is passed to the
|
|
.Cm scriptedpart
|
|
target to control disk setup.
|
|
Alternatively,
|
|
to use
|
|
.Cm zfsboot
|
|
instead of
|
|
.Cm partedit ,
|
|
the preamble can contain the variable
|
|
.Ev ZFSBOOT_DATASETS
|
|
instead of
|
|
.Ev PARTITIONS .
|
|
.Ss SETUP SCRIPT
|
|
Following the preamble is an optional shell script, beginning with a #!
|
|
declaration. This script will be run at the end of the installation process
|
|
inside a
|
|
.Xr chroot 8
|
|
environment in the newly installed system and can be used to set up
|
|
configuration files, install packages, etc. Note that newly configured
|
|
system services (e.g. networking) have not been started in the installed
|
|
system at this time and only installation host services are available.
