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

[Launchpad Bug Tracker]

This bug was fixed in the package livecd-rootfs - 2.774

---------------
livecd-rootfs (2.774) kinetic; urgency=medium

  * Remove modemmanager and udisks2 from cloud images in addition to fwupd.
    The use of tasks at install means all packages are marked manually
    installed in the apt database, so removing fwupd does not remove its
    dependencies.  LP: #1981109.

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.
