# zfs-mount This script will mount/umount the zfs filesystems.
#
# chkconfig: 2345 06 99
# description: This script will mount/umount the zfs filesystems during
# system boot/shutdown. Configuration of which filesystems
# should be mounted is handled by the zfs 'mountpoint' and
# 'canmount' properties. See the zfs(8) man page for details.
# It is also responsible for all userspace zfs services.
# probe: true
#
### BEGIN INIT INFO
# Provides: zfs-mount
# Required-Start: $local_fs zfs-import
# Required-Stop: $local_fs zfs-import
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# X-Stop-After: zfs-zed
# Short-Description: Mount ZFS filesystems and volumes
# Description: Run the `zfs mount -a` or `zfs umount -a` commands.
### END INIT INFO
#
# Released under the 2-clause BSD license.
#
# The original script that acted as a template for this script came from
# the Debian GNU/Linux kFreeBSD ZFS packages (which did not include a
# licensing stansa) in the commit dated Mar 24, 2011:
