Public bug reported:
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.
