systemd spams the syslog about lack of native systemd unit file

Hello Rolf and thanks for this bug report. I can't reproduce the issue you described neither on my laptop, which has been following Ubuntu "devel" for quite some cycles now, nor in a clean LXD container running Hirsute.

You brought freeradius as an example, but freeradius *does* ship with a systemd unit file:

  /lib/systemd/system/freeradius.service

So this looks like a local (mis)configuration issue to me. If you still think there's actually a bug here we need more information on how to reproduce it from a clean environment, otherwise it's difficult to confirm the problem or to begin working on it.

I'm marking this bug report as Incomplete for the moment.

I follow LTS-to-LTS normally and upgraded a btrfs subvolume copy all the way up to Hirsute now. I suspect that this is cruft from bionic or even earlier. I will look into it more as I find time. I usually don't boot into this hirsute system much.

Fixed in Debian with the introduction of a new quilt patch:

https://salsa.debian.org/systemd-team/systemd/-/commit/0c6d90f783093fc255e529f8a33b2ed2a8e6c2d6

Counting this as Fix Committed.

Also: setting all the other tasks to Invalid as there's noting wrong with them; the issue (and the fix) belong to systemd.

Hello Rolf, or anyone else affected,

Accepted systemd into groovy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/246.6-1ubuntu1.3 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-groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-groovy. 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.

In Groovy for 'legacy directory' logs, with /lib/systemd/system/dbus.socket manually edited to use /var/run... path to reproduce error, with current version logs seen e.g.:

with -proposed version, those logs are not present.

In focal, the 'native systemd unit' log is not present so the only message to check for is the 'legacy directory' message.
