unfortunately these things are deployed as appliance type arrangements
and are generally stashed in a cupboard/server room somewhere with no
input devices attached, only a power button.

I am using ext3 filesystem. Is there some way to do a fast recovery. I
notice that the older versions simply did a journal recovery and
bypassed the full scan. This has worked without problems for a
significant amount of time without corrupting the fs. Can i do something
similar rather than incurring a full scan every time it is shut down?
