I know your pain. On Linux, `mount -t ufs -o ufstype=44bsd` is what you're looking for. This requires that your system knows how to write UFS, which might be a problem. A possibly easier way to do this would be to boot off the memstick, remount root as rw, and make the change from the live memstick. I've seen some problems reading any new/modified files created by doing this from Linux (complains about bad inodes), but it seems to work from the BSD perspective... --- Elliot Robinson PGP Key: 9FEDE59A On Thu, Aug 21, 2014 at 8:37 PM, Martin G.
