# DESCRIPTION:
# 'zfs mount -l' should accept a valid key as it mounts the filesystem.
#
# STRATEGY:
# 1. Create an encrypted dataset
# 2. Unmount and unload the dataset's key
# 3. Verify the key is unloaded
# 4. Attempt to mount all datasets in the pool
# 5. Verify that no error code is produced
# 6. Verify that the encrypted dataset is not mounted
# 7. Attempt to load the key while mounting the dataset
# 8. Verify the key is loaded
# 9. Verify the dataset is mounted
