Even Sun rates their fsck at "10 minutes per gigabyte"... that
would mean a 3-hour fsck on my news server with Solaris. :-/ OTOH,
they have ODS 3.0 with journalled file systems which pretty much
eliminates boot up delays caused by inconsistent filesystems.

Waitaminute.... does it do this by default? It takes 10 minutes
to fsck the news server filesystems, and I'm pretty sure it only does
one drive at a time. It would be great if multiple fsck's could run
in parallel. Maybe my /etc/fstab isn't setup correctly?
