I don't think we can make changes that will damage a file system if someone boots an older kernel of the same major rev. (I can see the 2.1 post now: "I had a copy of 2.0R on floppy, so I booted that and...") Although I also suppose that there are sanity checks that prevent a UFS file system from being mounted as swap, right? Am I right that most scenarios where a file system is trashed are bugs that we can address? Peter -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
