[Bug 2067927] Re: systemd ships nice.conf override for wrong service

[Timo Aaltonen]

Hello Nick, or anyone else affected,

Accepted systemd into noble-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/255.4-1ubuntu8.2 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: systemd (Ubuntu Noble)
       Status: Triaged => Fix Committed

Title:
  systemd ships nice.conf override for wrong service

Status in systemd package in Ubuntu:
  Fix Committed
Status in systemd source package in Noble:
  Fix Committed

Bug description:
  [Impact]

  Prior to Noble (since Bionic or so), we shipped systemd-
  journald.service with Nice=-1 due to bug 1696970. In Noble, we
  intended to do this with a drop-in config instead of an out-of-tree
  patch [1]. But, this drop-in was mistakenly shipped for systemd-
  logind.service, instead of systemd-journald.service. This means the
  mitigation for bug 1696970 is no longer in place on Noble, and users
  could potentially see regressions.

  [Test]

  Check that systemd-journald.service has Nice=-1 configured (and that
  systemd-logind.service does not):

  $ systemctl show -p Nice systemd-journald.service 
  $ systemctl show -p Nice systemd-logind.service

  [Where problems could occur]

  Clearly, we should be careful that the drop-in is shipped for the
  correct service, otherwise we may apply the setting to the wrong unit.

  [Other information]

  I have not actually seen any regressions reported about this, but as
  we intended to keep the Nice=-1 setting for systemd-journald.service,
  we should restore it.
