Much like make(1), bsdinstall takes a target and possible parameters of the target as arguments. If invoked with no arguments, it will invoke the 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.
| | |
| Provide a path for the installation log file (overrides BSDINSTALL_LOG). See ENVIRONMENT VARIABLES for more information on BSDINSTALL_LOG. | |
| auto | Run the standard interactive installation, including disk partitioning. |
| jail destination | |
| Sets up a new chroot system at destination, suitable for use with jail(8). Behavior is generally similar to auto, except that disk partitioning and network setup are skipped and a kernel is not installed into the new system. | |
| script script | Runs the installation script at script. See SCRIPTING for more information on this target. |
| keymap | If the current controlling TTY is a syscons(4) or vt(4) console, asks the user to set the current keymap, and saves the result to the new system's rc.conf. |
| hostname | Prompts the user for a host name for the new system and saves the result to the new system's rc.conf. If BSDINSTALL_CONFIGCURRENT is set, also sets the host name of the current system. |
| netconfig | Interactively configures network interfaces (first invoking wlanconfig on wireless interfaces), saving the result to the new system's rc.conf and resolv.conf. If BSDINSTALL_CONFIGCURRENT is set, also configures the network interfaces of the current system to match. |
| autopart | Provides the installer's interactive guided disk partitioner for single-disk installations. Defaults to UFS. |
| bootconfig | Detects an appropriate partition and installs UEFI boot loader files. |
| zfsboot | Provides a ZFS-only automatic interactive disk partitioner. Creates a single zpool with separate datasets for /home, /tmp, /usr, /usr/ports, /usr/src, and /var. Optionally can set up geli(8) to encrypt the disk. |
| partedit | Provides the installer's interactive manual disk partitioner with an interface identical to 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. |
| scriptedpart parameters | |
|
Sets up disks like
autopart
and
partedit,
but non-interactively according to the disk setup specified in
parameters.
Each disk setup is specified by a three-part argument:
disk [scheme] [{partitions}] Multiple disk setups are separated by semicolons. The disk argument specifies the disk on which to operate (which will be erased), or the special value DEFAULT, which will result in either a selection window (as in autopart) for the destination disk or, if there is only one possible disk, will automatically select it. The scheme argument specifies the gpart(8) partition scheme to apply to the disk. If scheme is unspecified, scriptedpart will apply the default bootable scheme on your platform. The partitions argument is also optional and specifies how to partition disk. It consists of a comma-separated list of partitions to create enclosed in curly braces. Each partition declaration takes the form size type [mount point] 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 auto keyword causes the partition to take all the remaining space on the disk. The type option chooses the gpart(8) filesystem type, e.g., freebsd-ufs, freebsd-zfs, or freebsd-swap. The optional mount point argument sets where the created partition is to be mounted in the installed system. As an example, a typical invocation looks like: bsdinstall scriptedpart ada0 { 20G freebsd-ufs /, 4G freebsd-swap, 20G freebsd-ufs /var, auto freebsd-ufs /usr } Note that the list of partitions should not include boot partitions (e.g. EFI system partitions), which will be created automatically on whatever disk includes /. A shorter invocation to use the default partitioning (as autopart would have used) on the same disk: bsdinstall scriptedpart ada0 or, even shorter: bsdinstall scriptedpart DEFAULT | |
| mount | Mounts the file systems previously configured by autopart, partedit, or scriptedpart under BSDINSTALL_CHROOT. |
| distfetch | Fetches the distributions in DISTRIBUTIONS to BSDINSTALL_DISTDIR from BSDINSTALL_DISTSITE. |
| checksum | Verifies the checksums of the distributions listed in DISTRIBUTIONS against the distribution manifest. |
| distextract | Extracts the distributions listed in DISTRIBUTIONS into BSDINSTALL_CHROOT. |
| firmware | executes fwget(8) inside the BSDINSTALL_CHROOT to install any needed and available firmware for the new system. |
| rootpass | Interactively invokes passwd(1) in the new system to set the root user's password. |
| adduser | Interactively invokes adduser(8) in the new system. |
| time | Interactively sets the time, date, and time zone of the new system. |
| services | Queries the user for the system daemons to begin at system startup, writing the result into the new system's rc.conf. |
| entropy | Reads a small amount of data from /dev/random and stores it in a file in the new system's root directory. |
| config | Installs the configuration files destined for the new system, e.g., rc.conf(5) fragments generated by netconfig, etc.) onto the new system. |
| TMPDIR | The directory to use for temporary files. Default: " /tmp" |
| DISTRIBUTIONS | The set of distributions to install, e.g., "base.txz kernel.txz ports.txz". Default: unset |
| PARTITIONS | The partitioning of the disk onto which the system is being installed. See scriptedpart of the TARGETS section for format details. If this variable is unset, the installer will use the default partitioning as in autopart. Default: unset |
| BSDINSTALL_DISTDIR | The directory in which the distribution files can be found (or to which they should be downloaded). Default: " /usr/freebsd-dist" |
| BSDINSTALL_DISTSITE | |
| URL from which the distribution files should be downloaded if they are not already present in the directory defined by BSDINSTALL_DISTDIR. This should be a full path to the files, including architecture and release names. Most targets, e.g., auto and jail, that prompt for a FreeBSD mirror will skip that step if this variable is already defined in the environment. Example: https://download.freebsd.org/ftp/releases/powerpc/powerpc64/13.1-RELEASE/ or http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/amd64/12.2-RELEASE/. | |

This variable can take one of this values: stripe (No redundancy), mirror (n-Way mirroring), raid10 (RAID 1+0 - n x 2-Way Mirrors), raidz1 (RAID-Z1 - Single Redundancy RAID), raidz2 (RAID-Z2 - Double Redundancy RAID) or raidz3 (RAID-Z3 Triple Redundancy RAID). Default: "stripe" |
| ZFSBOOT_FORCE_4K_SECTORS | |

| If set and the installation is interactive, allow the user to confirm the layout before continuing with the installation. Default: "1" | |
Scripted installations follow an essentially identical path to interactive installations, though with some minor feature differences (for example, scripted installations do not support fetching of remote distribution files since scripted installations normally install the same files and the distributions can be added directly to the installation media). bsdinstall scripts consist of two parts: a preamble and a 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 chroot(8) in the newly installed system before bsdinstall exits. The two parts are separated by the usual script header (#!), which also sets the interpreter for the setup script.
A typical bsdinstall script, using the default filesystem layout and the UFS filesystem, looks like this:
PARTITIONS=DEFAULT DISTRIBUTIONS="kernel.txz base.txz"#!/bin/sh sysrc ifconfig_DEFAULT=DHCP sysrc sshd_enable=YES pkg install puppet
For a scripted installation involving a ZFS pool spanning multiple disks, the script instead looks like this:
DISTRIBUTIONS="kernel.txz base.txz" export ZFSBOOT_VDEV_TYPE=stripe export ZFSBOOT_DISKS="ada0 ada1" export nonInteractive="YES"#!/bin/sh echo "ifconfig_DEFAULT=DHCP" >> /etc/rc.conf echo "sshd_enable=YES" >> /etc/rc.conf pkg install puppet
On FreeBSD release media, such a script placed at /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 diskless(8) for details.
Alternatively, to use zfsboot instead of partedit, the preamble can contain the variable ZFSBOOT_DATASETS instead of PARTITIONS (see below). If using zfsboot, the variables ZFSBOOT_DISKS and ZFSBOOT_VDEV_TYPE must be set to create the pool of disks for the base system. Usually, for a mirrored booting disk, these two variables look like this:
ZFSBOOT_DISKS="ada0 ada1" ZFSBOOT_VDEV_TYPE=mirror
Remember to export all the variables for the zfsboot command, otherwise installation will fail.

The first column is the name of the dataset to be created as part of the ZFSBOOT_POOL_NAME pool and the remainder of each line contains the options to be set on each dataset. If multiple options are given, they can be separated by either commas or whitespace; everything following a pound/hash character is ignored as a comment.
mkdir release-media
tar -C release-media -xvf FreeBSD-13.0-RELEASE-amd64-disc1.iso
Then place a script as above in etc/installerconfig
This directory can then be used directly as an NFS root for diskless(8) installations or it can be rebuilt into an ISO image using the release scripts in /usr/src/release. For example, on amd64:
sh /usr/src/release/amd64/mkisoimages.sh -b '13_0_RELEASE_AMD64_CD' output.iso release-media
