[Bug 1981109] Re: server image pulls in ModemManager via fwupd, consumes 25MiB RAM in every container

[Steve Langasek]

I've also just discovered that in addition to the second-largest running
process (ModemManager), fwupd is responsible for the third-largest
running process (udisksd).  Perhaps it would be expedient to revisit the
inclusion of fwupd in the seed used for cloud and container images?

Title:
  server image pulls in ModemManager via fwupd, consumes 25MiB RAM in
  every container

Status in fwupd package in Ubuntu:
  New
Status in modemmanager package in Ubuntu:

Status in ubuntu-meta package in Ubuntu:

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.
