Which was plain stupid. :) You should _never_ ignore warnings, unless you know why you're ignoring it. (Q: Tell me at least three reasons why you should not use buffered devices for things like newfs, or tar(1) to a floppy.) This looks similar to the crashes/hangs reported by people for accessing floppies via the buffered device, in particular in error situations (like no floppy there at all). I've never been able to reproduce them. Perhaps i should also get the wrong habit of using the buffered devices... in the hope to see the bug some day, too. -- 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. ;-)
