.... [ Lots and lots of wonderful stuff deleted ] ... My $0.02 worth: The non-DEVFS system we have now is manual, with a throttle lever, mixture lever, and remote idle setting. DEVFS introduces computerized fuel injection & automatic transmissions I wholeheartedly agree with DEVFS, but can see where one would want some measure of control. Much of the discussion has been either in the theoretical, or the ``what if'' realm. I think there is a pragmatic, practical side to it too, which Terry seems to represent the most; If ALL devices that actually exist && have a driver to support them are represented in a DEVFS /dev, and if one can chmod, chown, chgrp and mv then (as far as renaming goes), then we can have a very persistent DEVS with a /etc/rc.something script. If you want it to look nicer, make the script a /etc/dev.conf, and ``parse it'' from /etc/rc, at the proper time, by applying all the deltas. this will be, from the system's point of view very persistent. Security? Anyone who can breach one file with proper root ownership & permissions can breach another. Thoughtless/careless/brainless administrators wil alwas exist and will always expose their systems. I say, let them. The only thing not clear to me (I know this is obvious), is; With an all DEVFS, can I still do ``mkdir -p /a/b/c/d;cd /a/b/c/d;mknod foo c 123 456, or its equivalent? If not, then symbolic links are fine too. Oh, a /dev DEVFS mounted, can it create links and/or symlinks? Why not? ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.708.7858 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
