Well, fsck-ing /var on a fully multiuser system is
hairy, at best, since /var is almost always being
written to by something or other.  Single user
mode is the simplest way of dealing with this, since
none of the logging, mail, or one of any of a 10^4
daemons will be trying to write to it, while you're
trying to fix it.

With mysql, I would assume* many of the same
problems with /usr (or /usr/local, if that is its own
filesystem).


*given that I know meow-all about mysql: where
it may wish to write, or what horrible perversions
it commits while running.
