# ID: zpool_create_020_pos
#
# DESCRIPTION:
#
# zpool create -R works as expected
#
# STRATEGY:
# 1. Create a -R altroot pool
# 2. Verify the pool is mounted at the correct location
# 3. Verify that cachefile=none for the pool
# 4. Verify that root=<mountpoint> for the pool
# 5. Verify that no reference to the pool is found in /etc/zfs/zpool.cache

#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-07-27)
#
# __stc_assertion_end
