# DESCRIPTION:
# User accounting upgrade should not be executed on readonly pool
#
# STRATEGY:
# 1. Create a pool with the feature@userobj_accounting disabled to simulate
#    a legacy pool from a previous ZFS version.
# 2. Create a file on the "legecy" dataset and store its checksum
# 3. Enable feature@userobj_accounting on the pool and verify it is only
#    "enabled" and not "active": upgrading starts when the filesystem is mounted
# 4. Export the pool and re-import is readonly, without mounting any filesystem
# 5. Try to mount the root dataset manually without the "ro" option, then verify
#    filesystem status and the pool feature status (not "active") to ensure the
#    pool "readonly" status is enforced.
