That's fine. But that's just a 'default', and what's being asked for here is support for overriding that default in a sensible fashion. Is that too much to ask for? > an example.. > I use 24 ptys.

You can do all this inside devfs. More operations: - Get all permission rules: # cat /dev/devrules >/tmp/rules - Get all special cases # cat /dev/devperms >/tmp/perms - Set a special case # chown dialer.uucp /dev/ttyd0 - Set all special cases # cat /tmp/perms /dev/devperms - Add new special cases # cat /tmp/extraperms >> /dev/devperms Really, how hard is this? Bear in mind that /dev/devrules and /dev/devperms aren't really files, but do use files for their backing storeage. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
