Is there a test suite that checks POSIX (or better yet, SUS v3)
compliance of a file system? That might prove useful, although I'm well
aware it'd probably require some brains (and kernel modules) to check
consistency guarantees. But apart from that, things like "truncate to
zero length does not change the mtime of a file" (fixed in ReiserFS only
some weeks ago) might get caught that way.
