# DESCRIPTION:
# Verify the hostid file can reside on a ZFS dataset.
#
# STRATEGY:
# 1. Create a non-redundant pool
# 2. Create an 'etc' dataset containing a valid hostid file
# 3. Create a file so the pool will have some contents
# 4. Verify multihost cannot be enabled until the /etc/hostid is linked
# 5. Verify vdevs may be attached and detached
# 6. Verify normal, cache, log and special vdevs can be added
# 7. Verify normal, cache, and log vdevs can be removed
