Oh, cool.  I hadn't actually gotten to looking at them yet.

Does anyone know how you figure out what optmizations or settings make
sense?  I have been wondering for years about some of these tweaks, but
it's really hard to find people who have even *looked* at the tunefs options.

Hmm.  Speaking of tunefs, was anyone working on integrating soft updates?
I know they've been integrated in FreeBSD and BSD/OS, so they must be at
least *possible* to integrate...
