Sure. Theoretically LFS should be able to be graceful about that
too, up to a point, but it's possible to break just about any file
system if you work hard enough at it.

Also, perhaps I misunderstood what Bill was saying, in light of
Jason's most recent response. Fwiw, I'm no part of releng, so I
probably shouldn't be speaking to what will or won't happen with ufs
for 1.6. It also sounds like I didn't quite understand the complexity
of UBC (I can see why it would be considerably more difficult atop
LFS than atop FFS).

Anyway, the bottom line is that LFS is good for partitions you want
to be able to write quickly to (including adding files) in bursts,
but which you won't need to go changing files around on very much.
Ideal for pkgsrc, not so for cvsroot. Which, I hope, isn't news to
