What happens on most Linux systems is that root file system gets
remounted read/only during the reboot/shutdown sequence, whil non-root
file systems are unmounted. I haven't tried 11.04 so I can't tell you
what it is doing. If it isn't umounting the non-root file systems, or
at least remounting the non-root file systems read/only, then
something is probably going wrong. That's a question for the
distribution....
