In terms of 386bsd, it might make more sense to simply hack "update" to
do a "sync()" more often than once every 30 seconds. Say, once every 2
seconds, which is what most of those silly DOS caches do.

Of course, you'll kill write performance for things that change a lot,
like directories when you're unpacking a "tar" or "cpio" archive, but
the filesystem will be "safer".

If you can stand horrible DOS-like disk write performance, that's probably
the right thing to do. [But if you can, why are you running Unix? ;-} ]
