# DESCRIPTION:
# Verify that if 'zfs mount -a' fails to mount one filesystem,
# the command fails with a non-zero error code, but all other
# filesystems are mounted.
#
# STRATEGY:
# 1. Create zfs filesystems
# 2. Unmount a leaf filesystem
# 3. Create a file in the above filesystem's mountpoint
# 4. Verify that 'zfs mount -a' succeeds if overlay=on and
# fails to mount the above if overlay=off
# 5. Verify that all other filesystems were mounted
#
