I'll definitely be considering that, as I already had to wait hours for
fsck to run on some 2 to 3TB ext3 filesystems after crashes. I know it
can be disabled, but I do feel better forcing a complete check after a
system crash, especially if the filesystem had been mounted for very
long, like a year or so, and heavily used.
