Automated selection of connections

[Alex Ferm <aferm petropower com>]

Hello all,

 I manage a bunch of cellular connected embedded devices running 
NetworkManager+ModemManager. I use the same software image on all 
devices regardless of which cell network they run on.

My current solution to selecting the appropriate connection pivots 
around the sim-operator-id (I'm running NM 1.0.6, so I had to write a 
dbus client to manage that).

My issue now is that we are switching to a private APN for one of our 
carriers. This will introduce a new connection configuration, however 
this time the sim-operator-id will be identical to one of our other options.

Is there a sane way to determine the correct APN to use without setting 
up connection configurations for every modem that goes out the door? I'd 
like to continue to be able to provide updates for devices deployed with 
the old APN without too much work as well.

I'd like to upgrade NM + MM on these devices, but that is not feasible 
in the near future.
