Wrong behavior. The desire here is not to disable checks due to being on
read-only media, but the filesystem is much less likely to incur damage
due to normally being read-only. The best example is /usr and sometimes
/, where it is *very* important to catch errors, but not all that likely
to incur them.

Which is why I wasn't writing about the mount count. I was writing about
the check interval/check time. With systems that reboot less than once a
month, the mount count will never be reached. Instead it will be the
check interval and worse yet, with infrequent reboots, *all* of the check
intervals will expire at once (even if they start spaced out, they will
tend to merge together).

I'm not. I'm pointing out the behavior needs more refinement.
