| # FS QA Test No. 199 |
| # |
| # Check that the features2 location fixups work correctly. We check both |
| # a regular read-write mount of a filesystem and the case where the |
| # filesystem is first mounted read-only and then later remounted read-write, |
| # which is the usual case for the root filesystem. |
