# 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' fails to mount the above if on Linux
#          or succeeds if on FreeBSD
#       5. Verify that all other filesystems were mounted
#
