For one, it was a known bug, so the PR wouldn't probably have caused more reason for anybody at all, and now, Bruce has fixed this bug a couple of days ago. Folks, nevertheless: Buffered devices (/dev/fd0) are JUST and ONLY for mounting something (and for swapon(8)). Raw devices (/dev/rfd0) are FOR EVERYTHING ELSE. (The terms `block device' and `character device' are misnomers you should never use. Historical errors.) Sorry for shouting, but from some non-newbie like dennis, i would have expected to know this. I'm repeating this over and over again to my clients on any Unix course i'm teaching. (There are several reasons for this statement, beyond the now fixed FreeBSD bug.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
