# DESCRIPTION:
# Test basic functionality of `zfs jail` and `zfs unjail`.
#
# STRATEGY:
# 1. Create a jail.
# 2. Perform some basic ZFS operations on a dataset both in the host and
#    in the jail to confirm the dataset is functional in the host
#    and hidden in in the jail.
# 3. Run `zfs jail` to expose the dataset in the jail.
# 4. Perform some basic ZFS operations on the dataset both in the host and
#    in the jail to confirm the dataset is functional in the jail and host.
# 5. Run `zfs unjail` to return the dataset to the host.
# 6. Perform some basic ZFS operations on the dataset both in the host and
#    in the jail to confirm the dataset is functional in the host
#    and hidden in in the jail.
