If the .Op Fl t flag is given, this takes effect only for the next boot. .It Xo .Cm check .Xc Performs a silent sanity check on the current system. If boot environments are supported and used, .Nm will exit with a status code of 0. Any other status code is not currently defined and may, in the future, grow special meaning for different degrees of sanity check failures. .It Xo .Cm create .Op Fl r .Op Fl e Brq Ar nonActiveBe | Ar beName Ns Cm @ Ns Ar snapshot .Ar newBeName .Xc Create a new boot environment named .Ar newBeName . .Pp If the .Fl r flag is given, a recursive boot environment will be made. .Pp If the .Fl e flag is specified, the new environment will be cloned from the given .Ar nonActiveBe or .Ar beName Ns Cm @ Ns Ar snapshot . Otherwise, the new environment will be created from the currently booted environment. .Pp If .Nm is creating from another boot environment, a snapshot of that boot environment will be created to clone from. .It Xo .Cm create .Op Fl r .Ar beName@snapshot .Xc Create a snapshot of the boot environment named .Ar beName . .Pp If the .Fl r flag is given, a recursive snapshot of the boot environment will be created. A snapshot is created for each descendant dataset of the boot environment. .Pp No new boot environment is created with this command. .It Xo .Cm destroy .Op Fl \&Fo .Ar beName Ns Op Cm @ Ns Ar snapshot .Xc Destroy the given .Ar beName boot environment or .Ar beName Ns Cm @ Ns Ar snapshot snapshot without confirmation, unlike in .Xr beadm 1 . Specifying .Fl F will automatically unmount without confirmation. .Pp By default, .Nm will warn that it is not destroying the origin of .Ar beName . The .Fl o flag may be specified to destroy the origin as well. .It Cm export Ar sourceBe Export .Ar sourceBe to .Xr stdout 4 . .Xr stdout 4 must be piped or redirected to a file. .It Cm import Ar targetBe Import .Ar targetBe from .Xr stdin 4 . .It Xo .Cm jail .Op Fl bU .Oo Bro Fl o Ar key Ns Cm = Ns Ar value | Fl u Ar key Brc Oc Ns ... .Ar beName .Op Ar utility Op Ar argument ... .Xc Create a jail of the given boot environment. Multiple .Fl o and .Fl u arguments may be specified. .Fl o will set a jail parameter, and .Fl u will unset a jail parameter. .Pp By default, jails are created in interactive mode and .Pa /bin/sh is executed within the jail. If .Ar utility is specified, it will be executed instead of .Pa /bin/sh . The jail will be destroyed and the boot environment unmounted when the command finishes executing, unless the .Fl U argument is specified. .Pp The .Fl b argument enables batch mode, thereby disabling interactive mode. The .Fl U argument will be ignored in batch mode. .Pp The .Va name , .Va host.hostname , and .Va path must be set, the default values are specified below. .Pp All .Ar key Ns Cm = Ns Ar value pairs are interpreted as jail parameters as described in .Xr jail 8 . The following default parameters are provided: .Bl -column "allow.mount.devfs" "" .It Va allow.mount Ta Cm true .It Va allow.mount.devfs Ta Cm true .It Va enforce_statfs Ta Cm 1 .It Va name Ta Set to jail ID. .It Va host.hostname Ta Va bootenv .It Va path Ta Set to a path in Pa /tmp generated by .Xr libbe 3 . .El .Pp All default parameters may be overwritten. .It Xo .Cm list .Op Fl DHas .Oo Bro Fl c Ar property | Fl C Ar property Brc Oc .Xc .Pp Display all boot environments.

Mount at the specified .Ar mountpoint if provided. .It Cm rename Ar origBeName newBeName Rename the given .Ar origBeName to the given .Ar newBeName . The boot environment will not be unmounted in order for this rename to occur. .It Cm ujail Bro Ar jailId | jailName Brc Ar beName .It Cm unjail Bro Ar jailId | jailName Brc Ar beName Destroy the jail created from the given boot environment. .It Xo .Cm umount .Op Fl f .Ar beName .Xc .It Xo .Cm unmount .Op Fl f .Ar beName .Xc Unmount the given boot environment, if it is mounted.

Upon failure, the target boot environment will be destroyed. In all cases, the running system is left untouched and a reboot into a partially updated system (due to install or hardware failure) cannot happen. Additionally, the full installation process requires only one reboot as it is performed in a new boot environment. .Pp .Nm requires a fully built world and kernel. It also requires .Xr beadm 1 and .Xr pkg 8 , which are not present in the base system and have to be installed manually. .Pp The .Ar options provided to .Nm are world and kernel flags like .Ev KERNCONF as described in .Xr build 7 . .Sh ENVIRONMENT User modifiable variables.
