I kind of doubt that'll change. If you want to see mount options, /proc/mounts is the place ... but then we don't show the defaults ;) I wonder if we should change that and be explicit about every option in /proc/mounts *shrug* > There seems to be much > confusion in the community due to lack of accurate information being > available.

As > is, AFAICT, there's no way to confirm these parameter values. /proc/mounts shows all mount options which were set differently from defaults. -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
