Hi Thomas, I'm not sure if there is a specific reason. However, seems to me like this would need careful consideration, given that what we usually want is for NM to retain IP addresses at least on wired, if it gets shutdown (e.g. the daemon is stopped or killed, etc.). Then you get into the question of how to deal with differenciating a user-initiatied *disconnect* rather than a shutdown of the daemon. You'll also get into the cases where you really want to disconnect for whatever reason, but want/need to retain your IP if possible. I think this is the most likely use case. I think this would probably be better served in your case by a dispatcher script: you can drop files in /etc/NetworkManager/dispatcher.d to have them run on various events; just take a look at 01ifupdown for inspiration; you should easily be able to do something like 'dhclient -r' from there to achieve the same thing. Otherwise, I guess you might want to ask on the NetworkManager list, which would be better suited for this kind of targetted question about this project.
