https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd/commit/?id=8c55289624c6f44beb2c5bbae78aabc074d36b1a
systemd (246.2-1) unstable; urgency=medium
* New upstream version 246.2
* Remove resolvconf.conf drop-in, resolved integration moved to resolvconf
package
* Rebase patches
* Add versioned Breaks against resolvconf (<< 1.83~) to systemd.
The PathExists= directive was changed in v246 to match the documented
behaviour but now causes resolvconf-pull-resolved.service to be
continuously triggered by resolvconf-pull-resolved.path.
This requires a fix in the resolvconf package, see #968015.
(Closes: #967906)
* Keep journal files compatible with older versions.
Disable the KEYED-HASH journal feature by default and keep LZ4 (instead
of ZSTD) as default compression for new journal files. Otherwise journal
files are incompatible and can't be read by older journalctl
implementations.
This patch can be dropped in bullseye+1, as journalctl from bullseye
will then be able to read journal files with those features.
(Closes: #968055)
systemd (246.1-1) unstable; urgency=medium
* New upstream version 246.1
* Rebase patches

Bug description:
Hi,
we had such cases in the past like bug 1817721 for bionic and maybe bug 1892130 is about the same as well. There were more but I didn't want to search for all of them - what I checked is that there are no open ones clearly pointing out the recent further drop in already flaky subtests.
In particular the tests "tests-in-lxd" and "systemd-fsckd" were known
to be flaky before, but got even worse.
Here stats of the last 40 runs, it might be a coincidences that this
is after 246-2ubuntu1 landed. Could as well be any other change

(I'm sure LP will make this unreadable, but is is nice in monospace)
Whatever the root cause is - the success rate of these has reduced so
much that the (even formerly questionable) practice of retry-until-
success won't work anymore.
I have run the two tests in a local VM and systemd-fsckd works there while tests-in-lxd seems to trip over the old flaky fellow being "boot-and-services".
We had the discussion in the past, but I think I need to again bring
up the suggestion to skip "tests-in-lxd" and "systemd-fsckd" until
they are on reasonable success rates.
