  24 # DESCRIPTION:
  25 #       Verify that if 'zfs mount -a' fails to mount one filesystem,
  26 #       the command fails with a non-zero error code, but all other
  27 #       filesystems are mounted.
  28 #
  29 # STRATEGY:
  30 #       1. Create zfs filesystems
  31 #       2. Unmount a leaf filesystem
  32 #       3. Create a file in the above filesystem's mountpoint
  33 #       4. Verify that 'zfs mount -a' fails to mount the above if on Linux
  34 #          or succeeds if on FreeBSD
  35 #       5. Verify that all other filesystems were mounted
