Comment 1 for bug 802782

This is a feature request I've already discussed shortly with Etienne Goyer.

Setting as Wishlist/Confirmed since I can acknowledge the issue, except there is a lack of easy ways to fix this.

Thinking back however, I'm certain there is a way of at least patching NM so that the default wired connections usually created automatically would not be, which will allow you to have new devices not automatically build connections and activate, but still allow creating them manually when needed. Since patching this is possible then it should be relatively simple to also make that optional and dependant on a gconf/dconf key (which would default to the current behavior).
