  34 # DESCRIPTION:
  35 # Creating and writing xattrs on files in snapshot directories fails. Also,
  36 # we shouldn't be able to list the xattrs of files in snapshots who didn't have
  37 # xattrs when the snapshot was created (the xattr namespace wouldn't have been
  38 # created yet, and snapshots are read-only) See fsattr(5) for more details.
  39 #
  40 # STRATEGY:
  41 #       1. Create a file and add an xattr to it.
  42 #       2. Create another file, but don't add an xattr to it.
  43 #       3. Snapshot the filesystem
  44 #       4. Verify we're unable to alter the xattr on the first file
  45 #       5. Verify we're unable to list the xattrs on the second file
