As a man who took his filesystems into his own hands...
The official reason for avoiding ufs in 1.1 is that it CAN panic
the kernel if your inode/second ratio gets too high, i.e.
unbatching or expiring news.... I use /home for my source code
and home directory. I have yet to panic 1.1 due to ufs. So,
if the filesystem can keep inode usage to a slow pace, you
should be safe. I'd be wary of making a ufs partition a fileserver
area though, the inode use could be fast enough to cause problems.
I'd try it for a while and see how it works, due to the nature
of the problem, your milage will most certainly vary. It depends
totally on the usage characteristics from what I've heard.
C= may correct my simplistic interpretation of the problem.
