These days, for me, it's pretty much all ZFS
One of ZFS's particularly lovely features was that there was no offline filesystem
checker at all. So if you have a filesystem (pool, whatever) which you think something
bad might have happened to, you check it *by mounting it*, where the checker runs *in the
kernel, so any serious error in the code means a panic, if you're lucky and something
worse if you're not.
When I found out about this I thought seriously of shorting Sun's stock (if I knew
how to do that). I would have made money. As it was we stuck with logged UFS which, by
2007 or so was seriously bulletproof.
