I doubt there is a software soution against this (one that does not
depend on a transactional file system, of course). What prevents you
from using a UPS? I'd say that a sudden power-loss is by far the least
probable error cause for a system that is configured to do any serious
work.

Please elaborate why you (or others ;)) consider this case important.
