they create a file named /fastboot, and /etc/rc (which deals with things
like fsck'ing the disk on startup), upon seeing it, doesn't fsck the disk.

umm, it's *really* a good idea to do this *ONLY* if you know the
disks were unmounted cleanly (for an example of why,
say "fastboot" but reset the machine before it syncs the disks).

even so, you don't want to *always* not fsck your disks, because,
while the FFS has been around for ages, it still might
have a few bugs in it...


so use fastboot whenever you can, but make *sure* that things get
fsck'd after crashes...
