37#
38# DESCRIPTION:
39# Creating and writing xattrs on files in snapshot directories fails. Also,
40# we shouldn't be able to list the xattrs of files in snapshots who didn't have
41# xattrs when the snapshot was created (the xattr namespace wouldn't have been
42# created yet, and snapshots are read-only) See fsattr(5) for more details.
43#
44# STRATEGY:
45#	1. Create a file and add an xattr to it.
46#	2. Create another file, but don't add an xattr to it.
47#       3. Snapshot the filesystem
48#	4. Verify we're unable to alter the xattr on the first file
49#	5. Verify we're unable to list the xattrs on the second file
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2006-12-13)
