Thanks. i don't hibernate, but i still like 1-to-1 or so mapping of swap to RAM, mainly because swap space is the backing store for tmpfs and any low-mem situations ... i've had OOM killer come in and murder stuff i really wished it wouldn't have, and if tmpfs does happen to fill (i've done it multiple times) things are "nicer" when swap is around to relieve pressure, because tmpfs files can simply be swapped out if not in use. i also had a really nasty webkit bug that took ~3 days to track, and it turned out to be due to lack of swap -- linux kernel disables or at least limits memory overcommit when swap is not present: http://trac.webkit.org/changeset/86957 -- so now i keep some around just so things are smoother. -- C Anthony
