Updated the bug description to be SRUable.
** Description changed:
+ [Impact]
+
+ Cloud images should not have fwupd, modemmanager, and udisks2 installed
+ as those are not needed and only taking up memory.
+
+ [Test Case]
+
+ Build cloud images with livecd-rootfs and confirm that fwupd,
+ modemmanager, and udisks2 are not present and not running.
+
+ [Regression Potential]
+
+ Only thing that might happen is for any of the 3 listed packages getting
+ removed from images where they might be used. So possibly double-
+ checking if this will affect preinstalled server images and if they care
+ about this or not.
+
+ [Original 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.
** Changed in: livecd-rootfs (Ubuntu Jammy)
Status: Triaged => Fix Committed
** Tags added: verification-needed verification-needed-jammy
