Removing ZFS Delegated Permissions (zfs unallow)

You can remove previously delegated permissions with the zfs unallow command.

For example, assume that you delegated create, destroy, mount, and snapshot permissions as follows:

$ zfs allow mindy create,destroy,mount,snapshot system1/home/mindy
$ zfs allow system1/home/mindy
---- Permissions on system1/home/mindy ----------------------------------
Local+descendant permissions:
user mindy create,destroy,mount,snapshot

To remove these permissions, you would use the following syntax:

$ zfs unallow mindy system1/home/mindy
$ zfs allow system1/home/mindy
