If that's what you're trying to do, then staggering the forced fsck timings
isn't going to help you at all.
fsck on boot can occur in two occasions: either it needs to be done
because you hit the max mount count or max unchecked timeout, or it
needs to be done because you previously umounted uncleanly and it can't
be fixed by replaying the ext3 journal (either because it got corrupted,
or because you're running ext2 and there is no journal).
