I don't see how we can do the fallback stuff with our current infrastructure. You could do it with profile.sh, but our current infrastructure isn't really suited to it. In some ways what we really need is an all knowing IPv4 address configuration program that can probe the link and decide if it should a) use a static IP, b) use DHCP, or c) use an LLA. It's possible we could do this in a shell script, but I'm not sure we'd want to. -- Brooks --UfEAyuTBtIjiZzX6 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFE7MbFXY6L6fI4GtQRApwfAKC015TZUTHng/4OPmCqYTo8UWOfVQCeLZcz wYBpTfHzggq7ThCTpO6OgAc= =umaF -----END PGP SIGNATURE----- --UfEAyuTBtIjiZzX6--
