Bug description:
Looking at memory utilization in a pristine Ubuntu lxd container (top
-o RES), I see that ModemManager is running, which I was surprised to
see is present at all in the stock image.
Tracking this I find that fwupd depends on libmm-glib0, which in turn
Recommends: modemmanager.
Libraries in general should not recommend daemons, so it's possible
this should be fixed by libmm-glib0 dropping this Recommends. It
certainly doesn't seem to be a deliberate decision by the Server Team
to have modemmanager installed and running by default on all systems.
