This in itself is a bad thing, because you then don't get to find random bit-flip data corruptions (which is what the regular fsck-on-boot is for). To get the same effect with no impact on boot times, keep your filesystems in LVM, take a snapshot of each filesystem at regular intervals, and then run fsck on the snapshot. (This advice came from Ted Ts'o, who knows a thing or two about filesystems... :) ) Hugo. -- === Hugo Mills: h...@... carfax.org.uk | darksatanic.net | lug.org.uk === PGP key: 515C238D from wwwkeys.eu.pgp.net or http://www.carfax.org.uk --- emacs: Eighty Megabytes And Constantly Swapping. ---
