Modification of the on disk format of UFS was pretty much require for fast labeling of ondisk content (lableing of UFS1 file systems, is possiable, but VERY expensive because the labels are stored in a file like quotas), but that's only a small part of the work involved in making a trusted OS. UFS2 made many more changes then were required for TrustedBSD because a need to break binary compatability was seen as a good time to fix all the 32-bit crap in the ondisk format so we could have >>1TB file systems. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
