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