Comment 3 for bug 12115

That's not the behavior it's supposed to have:

- The activate and deactivate buttons are supposed to do both ifup/ifdown and to
add/remove the auto stanza (the latter happens when you close the tool clicking OK)
- The "this interface is configured" checkbutton is meant to just deconfigure
the interface (i.e.: I have a wifi and an ethernet interface, 2 profiles, and I
don't want both configured at the same time), that's why the whole interface
dialog turns insensitive

With this for example you'll be able to ifdown an interface (when you don't need
it) and keep it down even through reboots (which is a pretty consistent behavior
IMHO) and to remove unneeded interfaces from your configuration

maybe the "this interface is configured" string should be more clear, but I
couldn't think of a better one...
