# DESCRIPTION:
# Verify that 'zfs unshare [-a] <filesystem|mountpoint>' is aware of legacy share.
#
# STRATEGY:
# 1. Set 'zfs set sharenfs=off'
# 2. Use 'share' to share given filesystem
# 3. Verify that 'zfs unshare <filesystem|mountpoint>' is aware of legacy share
# 4. Verify that 'zfs unshare -a' is aware of legacy share.
