E.g., fsck_msdosfs always (except with -n of course) claims to fix up the dirty flag if it is set, but doesn't actually do so unless the FAT needs to be written to fix some other problem. > A few weeks ago I had started to take an deeper look into the darwin sources > especially into msdosfs.

More than 50% of it is to undo FreeBSD changes. E.g., it reverses old changes to remove __P(()) and atari support. A diff relative to the 2000/08/28 version of -current is only 140K. Bruce
