Looking through the code, this really looks fixed if not in Karmic, then definitely in Lucid and later releases. That's what the "no-auto- default=<mac address>," key in /etc/NetworkManager/nm-system- settings.conf is for, and is automatically added when Auto eth0 is created so that it doesn't get re-added if deleted.
Since we're talking wildly different code between 0.7 and 0.8, please open a new bug using ubuntu-bug (and tell us the number here) if you see that it is still broken in Karmic or Lucid. ** Changed in: network-manager (Ubuntu) Status: Confirmed => Fix Released -- Undeletable and unchangeable "auto eth0" connection https://bugs.launchpad.net/bugs/306469 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
