It's on my list of things to look at.

You may have noticed that I've been syncing in various changes to ffs
from FreeBSD & OpenBSD, such that our superblocks are now `in sync'
(although we don't have ffs snapshots, the appropriate superblock fields
have been reserved).

Regarding the growfs problem, there's two solutions I see:

	- import FreeBSD's "growfs" (and ffsinfo):
		Pros:	it works
		Cons:	it's grow only

	- import der Mouse's "resizefs":
		Pros:	it can shrink as well as grow
		Cons:	it has bugs, which need fixing first

I'm leaning towards the latter, because the ability to shrink a file
system is useful. If that turns out to be ``too much work'', I can
always fall back to the FreeBSD stuff if necessary.
