As it's an age-old topic:  An unskilled setting of the passno column in the
fstab can actually make the fsck take longer.  If it's 1 chunk (plus one for
swap) you're guaranteed that the fsck of all relevant filesystems will be
done as quickly as possible.  (Note too that if DocumentRoot or /var/mail
(as examples) are on one of those partitions, you need to fix-up the rc.d
dependencies so apps don't start without their data.

In order for the multi-partitions where the non-critical filesystems
wouldn't get fsck'd, the fstab entry would need a 'noauto' and then some
late-boot scripts that initiate the fsck and then mount the partitions.  If
you're adept at configuring the fstab rc.d scripts correctly, you could
stand large gains in quickly getting the system responsive but there would
be the overhead to let it boot without intervention.
