ReiserFS indeed has a bad reputation in that regard. XFS' reputation is not entirely deserved, but not entirely undeserved either. It assumes that there is a UPS, and that the filesystem will always be unmounted cleanly. If that doesn't happen, then files of which data and/or metadata was in flight when the system went down unexpectedly will be zeroed, rather than corrupt. It would've been nice if that had been a tunable parameter rather than an unmodifiable thing, but other than that it's not an entirely unreasonable thing to do. -- The biometric identification system at the gates of the CIA headquarters works because there's a guard with a large gun making sure no one is trying to fool the system. http://www.schneier.com/blog/archives/2009/01/biometrics.html _______________________________________________ Debconf-video mailing list [email protected] http://lists.debconf.org/mailman/listinfo/debconf-video
