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(7) 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
