F38 Change: Shorter Shutdown Timer

[dustymabe]

For the proposed Fedora 38 changes we decided to discuss further the following change:

• Shorter Shutdown Timer
  • A downstream configuration change to reduce the systemd unit timeout from 2 minutes to 45 seconds and send SIGABRT to generate a core dump before SIGKILL.
  • Tracking bug: #2161753
  • NOTES: DM: We will need to consider the shutdown timeout change and if we want to accept it or add our own configuration override.

I think we should not make this change for Fedora CoreOS. I commented on the list https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/K7YXBE35NJZIA5TGDC5OPNZHU6SWGE5N/

I agree as well that we should not make this change for FCOS, which means that we'll have to make sure to reset the setting to the default.

• Effective change: https://src.fedoraproject.org/rpms/systemd/c/ba02e904964116b848080ca72243174f4ef3eced?branch=rawhide

As this is set by default at compile time, we'll have to ship a config to revert it.

We discussed this in today's community meeting:

  * AGREED: we do not want this change in FCOS. we think other server
    variants don't as well. we will submit a PR against fedora-release
    to undo this change on server variants to try to push the
    conversation forward.  (jlebon, 17:05:52)

Feel free to ping folks from other editions there a I'm not sure exactly who to ping.

It would be nice to have a test for it. It should be easy to make by checking systemctl show values.

I've manually tested the RPM. I'll let Adam write the kola test.
