Generally, if using NetworkManager, you do not want your interfaces
upped on boot.  The current NM only goes to work when a user logs into
an X session.  Then it connects to the wired interface (if available) or
to the WAP in range that it had connected to most recently.  If no
previous connection, it waits for the user to pick one.

Future versions of NM will support a global connection profile that will
work on boot rather than at login.  Meanwhile, if you want a connection
at boot time, don't use NM.

Whether this all works reliably as intended depends on driver support.
Currently, for example, iwl3945 won't connect through NM when SSIDs are
hidden (without sacrificing a goat and two rabbits).
