6 | # description: This script will mount/umount the zfs filesystems during | |
7 | # system boot/shutdown. Configuration of which filesystems | |
8 | # should be mounted is handled by the zfs 'mountpoint' and | |
9 | # 'canmount' properties. See the zfs(8) man page for details. | |
10 | # It is also responsible for all userspace zfs services. | |
