Although still NOT recommended, I have had great luck with using the
ext3 (with journalizing) and the Reiser file systems on Linux.  They
more or less act like the transaction systems on a database.  The
transaction replay times on reboot are usually less than a second for
several filesystems.  So far, absolutely NO data loss has happened to me
during power failures, or just plain screw ups on my part.

Hope this helps!
