- Other than the fact that when I tried this, DCFFS proved to be very unstable,

- invalidation problems. Furthermore, ReOrg crashed every time I tried to reset
- the hard disk to FFS - I was forced to go the backup, reformat, restore route.
- Grrr.

- DCFFS is _not_ safe - it has serious bugs in many OS versions. I think it is
- reasonably safe under 3.0, but badly broken under 3.1, which is what I (and a
- lot of other people) use.

- Now, if you're prepared to put up with this risk just for faster directory
- scans (noting that the directory cache actually _slows down_ just about any
- other disk operation), go ahead. I don't think it's worth it (in retrospect,
- of course - I did think it was worth it in the first place... ;)
