The submitter of #798893 provides a reason why this should be implemented. Suppose you have a laptop with a worthless built-in Wi-Fi card. You want to disable it so that you can use another device, but NM re-enables it on every boot (... ... and then insists on routing traffic to it, breaking network service).
** Summary changed: - Network state always returns to "on", despite state set at last Shutdown + NM re-enables interfaces that were disabled before reboot -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/392026 Title: NM re-enables interfaces that were disabled before reboot Status in One Hundred Paper Cuts: Invalid Status in “network-manager” package in Ubuntu: Triaged Bug description: This is particularly annoying in UNR where it affects battery life. But it could also be aggravating on the desktop if you don't want a machine to connect to Wired or Wireless Network without your permission at boot. Network manager always returns to a default "On" state at boot. It would be nice that if you deliberately disabled either wireless, or networking before shut down, that Ubuntu would remember this setting and boot up in the same state that you shut down.
