You can remove previously granted permissions with the zfs unallow command.
For example, assume that you delegated create, destroy, mount, and snapshot permissions as follows:
# zfs allow cindys create,destroy,mount,snapshot tank/cindys # zfs allow tank/cindys ------------------------------------------------------------- Local+Descendent permissions on (tank/cindys) user cindys create,destroy,mount,snapshot ------------------------------------------------------------- |
To remove these permissions, you would need to use syntax similar to the following:
# zfs unallow cindys tank/cindys # zfs allow tank/cindys |
