+.Dt ZFSBOOTCFG 8
+.Os
+.Sh NAME
+.Nm zfsbootcfg
+.Nd "specify zfsboot options for next reboot"
+.Sh SYNOPSIS
+.Nm
+.Ao Ar options Ac
+.Sh DESCRIPTION
+.Nm
+is used to set
+.Xr boot.config 5
+style options to be used by
+.Xr zfsboot 8
+or
+.Xr gptzfsboot 8
+the next time the machine is booted.
+Once
+.Xr zfsboot 8
+or
+.Xr gptzfsboot 8
+reads the information, it is deleted.
+If booting fails the machine automatically reverts to the previous
+boot configuration for the next boot.
+The information is stored in a special reserved area of a ZFS pool.
+.Xr zfsboot 8
+or
+.Xr gptzfsboot 8
+read the boot options information from the first disk found in the first
+ZFS pool found.
+.Sh ENVIRONMENT
+.Bl -tag -width vfs.zfs.boot.primary_pool -compact
+.It Ev vfs.zfs.boot.primary_pool
+The
+.Xr kenv 1
+variable that identifies a pool for which the options are written.
+.It Ev vfs.zfs.boot.primary_vdev
+The
+.Xr kenv 1
+variable that identifies a disk within the pool where the options
+are written.
+.El
+.Sh EXAMPLES
+Try to boot to a new
+.Em boot environment
+without changing the
+.Cm bootfs
+property of a pool:
+.Pp
+.Dl "zfsbootcfg ""zfs:tank/ROOT/newbe:""
+.Pp
+To clear the boot options:
+.Pp
+.Dl "zfsbootcfg """"
+.Sh SEE ALSO
+.Xr boot.config 5 ,
+.Xr gptzfsboot 8 ,
+.Xr zfsboot 8
+.Sh HISTORY
+.Nm
+appeared in
+.Fx 12.0 .
+.Sh AUTHORS
+This manual page was written by
+.An Andriy Gapon Aq Mt avg@FreeBSD.org .
+.Sh CAVEATS
+At the moment,
+.Nm
+uses the
+.Ev vfs.zfs.boot.primary_pool
+and
+.Ev vfs.zfs.boot.primary_vdev
+.Xr kenv 1
+variables to determine a ZFS pool and a disk in it where the options
+are to be stored.
+The variables are set by the ZFS boot chain, so there is an assumption
+that the same boot disk is going to be used for the next reboot.
+There is no
+.Nm
+option to specify a different pool or a different disk.
+.Pp
+.Nm
+should be extended to install new
+.Xr zfsboot 8
+blocks in a ZFS pool.
