When NM starts up, it will take over devices and in most cases (except
for wired) will deactivate them to bring them back to a clean state.
For anything other than wired, there's a crap-ton of state that NM would
need to read and acquire if it just took over the existing wifi
connection or whatever.  That includes supplicant state, possibly a
dhclient instance, maybe even PPPoE.  Most of these things don't export
a dbus interface, and thus it's even harder to get that state on startup
and seamlessly "take over" the interface.  Second, NM usually gets
started at boot time, so it's not really an issue, and people don't
usually restart NM while the system is up.

So this is normal on NM start.  What you're probably wondering is why
nothing gets connected *after* this point.  Which Jiri posted some
questions about...
