- That's silly... in a lot of modern OSes the whole /filesystem/ isn't part
- of the "kernel". (I'm not sure about NeXTstep as it's based on Mach 2.5,
- but under Mach 3.0 the filesystem is usually a user process.)

- So what? The NeXT uses the BSD filesystem, but the OS isn't even Unix.
- In terms of "pure" unix philosophy you're right, but there hasn't been
- a /pure/ Unix since the Sixth (or maybe Seventh) Edition.

- It is? Reliably? Please demonstrate!
