# DESCRIPTION: Unmounted canmount=noauto export is removed during zfs share -a
#
# STRATEGY:
# 1. Share a dataset that also has canmount set to noauto
# 2. Capture the zfs exports file when the dataset is mounted + shared
# 3. Simulate a reboot by unmounting the dataset and restoring the exports file
# 4. Verify that 'zfs share -a' removes the export since dataset is not mounted
#

dataset="$TESTPOOL/$TESTFS"
mountpt=$(get_prop mountpoint $dataset)
function cleanup
{
zfs set canmount=on $dataset
zfs set sharenfs=off $dataset
zfs mount -a
#
# unset __ZFS_POOL_EXCLUDE so that we include all file systems when
# rebuilding the exports file
#
unset __ZFS_POOL_EXCLUDE
rm /etc/exports.d/zfs.exports
zfs share -a
