35# DESCRIPTION:
36# Verify that 'zfs unshare [-a] <filesystem|mountpoint>' is aware of legacy share.
37#
38# STRATEGY:
39# 1. Set 'zfs set sharenfs=off'
40# 2. Use 'share' to share given filesystem
41# 3. Verify that 'zfs unshare <filesystem|mountpoint>' is aware of legacy share
42# 4. Verify that 'zfs unshare -a' is aware of legacy share.
