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 bootconfig +Detects an appropriate partition and installs UEFI boot loader files. .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., .Xr rc.conf 5 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.txz kernel.txz ports.txz". Default: unset +.It Ev PARTITIONS +The partitioning of the disk onto which the system is being installed. +See +.Cm scriptedpart +of +the +.Sx TARGETS +section for format details. +Default: unset .It Ev BSDINSTALL_DISTDIR The directory in which the distribution files can be found (or to which they should be downloaded). Default: .Dq 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: .Dq Pa /mnt .It Ev BSDINSTALL_LOG Path to a log file for the installation. Default: .Dq 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: .Dq 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: .Dq Pa /tmp/bsdinstall_boot .It Ev ZFSBOOT_POOL_NAME Name for the pool containing the base system. Default: .Dq zroot .It Ev ZFSBOOT_POOL_CREATE_OPTIONS Options to be used when creating the base system's pool. Each option must be followed by the -O flag to be taken into consideration or the pool will not be created due to errors using the command .Cm zpool . Default: .Dq Li "-O compress=lz4 -O atime=off" .It Ev ZFSBOOT_BEROOT_NAME Name for the boot environment parent dataset. This is a non-mountable dataset meant to be a parent dataset where different boot environment are going to be created. Default: .Dq ROOT .It Ev ZFSBOOT_BOOTFS_NAME Name for the primary boot environment, which will be the default boot environment for the system. Default: .Dq default .It Ev ZFSBOOT_VDEV_TYPE The type of pool to be created for the base system. This variable can take one of this values: stripe (No redundacy), mirror (n-Way mirroring), raid10 (RAID 1+0 - n x 2-Way Mirrors), raidz1 (RAID-Z1 - Single Redundacy RAID), raidz2 (RAID-Z2 - Double Redundacy RAID) or raidz3 (RAID-Z3 Triple Redundacy RAID). Default: .Dq stripe .It Ev ZFSBOOT_FORCE_4K_SECTORS Indicates either the pool will use 4K or 512 sectors. If this variable is not empty, 4K sectors will be used. Default: .Dq 1 .It Ev ZFSBOOT_GELI_ENCRYPTION If this variable is not empty, it will use .Xr geli 8 to encrypt the root pool, enabling automatically the .Ev ZFSBOOT_BOOT_POOL variable. Default: .Dq "" .It Ev ZFSBOOT_GELI_KEY_FILE Path to the .Xr geli 8 keyfile used to encrypt the pool where the base system is stored. Default: .Dq Pa /boot/encryption.key .It Ev ZFSBOOT_BOOT_POOL If set a separated boot pool will be created for the kernel of the system and .Xr loader 8 . Default: unset .It Ev ZFSBOOT_BOOT_POOL_CREATE_OPTIONS Options to use when creating the boot pool, when enabled (See .Ev ZFSBOOT_BOOT_POOL ). Default: unset .It Ev ZFSBOOT_BOOT_POOL_NAME Name for the optional boot pool when it is enabled, (See .Ev ZFSBOOT_BOOT_POOL ). Default: .Dq bootpool .It Ev ZFSBOOT_BOOT_POOL_SIZE Size of the boot pool when it is enabled (See .Ev ZFSBOOT_BOOT_POOL ). Default: .Dq 2g .It Ev ZFSBOOT_DISKS Disks to be used for the base system, including the boot pool. This variable must only be used on a scripted installation. See .Sx SCRIPTING for more information. Default: unset .It Ev ZFSBOOT_SWAP_SIZE Size of the swap partition on each block device. This variable will be passed to .Xr gpart 8 ; which supports SI unit suffixes. Default: .Dq 2g .It Ev ZFSBOOT_SWAP_ENCRYPTION If set, enables the encryption of the swap partition using .Xr geli 8 . Default: "" .It Ev ZFSBOOT_SWAP_MIRROR If set, enables a swap mirroring using .Xr gmirror 8 . Default: unset .It Ev ZFSBOOT_DATASETS ZFS datasets to be created on the root zpool, it requires the following datasets: .Pa /tmp , .Pa /var/tmp , .Pa /$ZFSBOOT_BEROOT_NAME/$ZFSBOOT_BOOTFS_NAME . See .Sx ZFS DATASETS for more information about who to write this variable and to take a look into the default value of it. .It Ev ZFSBOOT_CONFIRM_LAYOUT If set and the installation is interactive, allow the user to confirm the layout before continuing with the installation. Default: .Dq 1 .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 +gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0 sysrc ifconfig_em0=DHCP sysrc sshd_enable=YES pkg install puppet .Ed .Pp For a ZFS scripted installation, the script looks like this: .Bd -literal -offset indent DISTRIBUTIONS="kernel.txz base.txz" export ZFSBOOT_VDEV_TYPE=stripe export ZFSBOOT_DISKS=ada0 export nonInteractive="YES" #!/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 , and setting the variables .Ev ZFSBOOT_DISKS and .Ev ZFSBOOT_VDEV_TYPE to create the pool of disks for the base system. Usually, for a mirrored booting disk, this two variables looks like this: .Bd -literal -offset indent ZFSBOOT_DISKS="ada0 ada1" ZFSBOOT_VDEV_TYPE=mirror .Ed .Pp Remenber to export all the variables for the .Cm zfsboot command, otherwise it will not get set. .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. .Ss ZFS DATASETS The .Cm zfsboot partitioning takes the .Ev ZFSBOOT_DATASETS variable to create the datasets on the base system. This variable can get pretty huge if the pool contains a lot of datasets. The default value of the .Ev ZFSBOOT_DATASETS looks like this: .Bd -literal -offset indent # DATASET OPTIONS (comma or space separated; or both) # Boot Environment [BE] root and default boot dataset /$ZFSBOOT_BEROOT_NAME mountpoint=none /$ZFSBOOT_BEROOT_NAME/$ZFSBOOT_BOOTFS_NAME mountpoint=/ # Compress /tmp, allow exec but not setuid /tmp mountpoint=/tmp,exec=on,setuid=off # Do not mount /usr so that 'base' files go to the BEROOT /usr mountpoint=/usr,canmount=off # Home directories separated so they are common to all BEs /usr/home # NB: /home is a symlink to /usr/home # Ports tree /usr/ports setuid=off # Source tree (compressed) /usr/src # Create /var and friends /var mountpoint=/var,canmount=off /var/audit exec=off,setuid=off /var/crash exec=off,setuid=off /var/log exec=off,setuid=off /var/mail atime=on /var/tmp setuid=off .Ed .Pp The first column if the dataset to be created on the top of the .Ev ZFSBOOT_POOL_NAME and the rest of the columns are the options to be set on each dataset. The options must be written on a coma or space separated list, or both. And everything behind a pound/hash character is ignored as a comment. .Sh HISTORY This version of .Nm first appeared in .Fx 9.0 . .Sh AUTHORS .An Nathan Whitehorn Aq Mt nwhitehorn@FreeBSD.org Index: stable/12 =================================================================== --- stable/12 (revision 358957) +++ stable/12 (revision 358958) Property changes on: stable/12 ___________________________________________________________________ Modified: svn:mergeinfo ## -0,0 +0,1 ## Merged /head:r357638
