Are there any documents out there that go through how to minimize disk usage?

I think I'd rather not turn off my syslog, but I'd be willing to give
up, say, a few hundred k of memory to write it to via a mfs. But I'm
not smart enough to know how to ensure it doesn't fill up the mfs and
cause problems... If that's even a problem.

Anything else that accesses the disk on a regular basis? Does softdeps
have anything to do with this? Again, I'm not super smart about this
subject, but it might be nice to span out any syncs it does or
something like that.

I'd like to document this in my Mobilepro 880 howto, which could
probably quite easily be morphed into a NetBSD on your PDA howto at
some point.
