Mount-Optionen "noatime" und "nodiratime" und die Werte von
/proc/sys/vm/* anpassen (die in die /etc/sysctl.conf packen), vor allem
die dirty*-Sachen und da vor allem dirty_expire_centisecs and
dirty_writeback_centisecs.

Aber es gilt der Kommentar aus dem noflushd:

* But what if someone pulls the plug while the disk is spun down?

You lose. That's the risk you have to take. It's entirely up to you to decide
between the risk and the noise. Take into account if you're about to install
noflushd on your notebook that's rather immune to power glitches and kernel
bugs, or on your kernel devel machine crashing twice a day, where you're about
to write your PhD thesis... That said, remember that you can always forcefully
commit your data to disk. Just type 'sync' if you don't want to lose your
100MB download to a flaky fuse.
