Code review comment for ~slyon/ubuntu/+source/systemd:lunar/no-i386-binaries

I've uploaded a new build to the ppa:ci-train-ppa-service/4635 for Mantic.

The ppc64el build fails in the same way the current version in Lunar fails on Mantic (so this seems unrelated):
https://launchpad.net/~slyon/+archive/ubuntu/testing/+sourcepub/14739488/+listing-archive-extra

Some autopkgtests can be found here:
https://autopkgtest.ubuntu.com/results/autopkgtest-mantic-ci-train-ppa-service-4635/?format=plain

i386 reverse depends spot checks are looking good:
(libsystemd0) dbus-broker PASS
(libudev1) bluez PASS

Normal systemd autopkgtests fail the "tests-in-lxd" case, the same way they fail in Mantic, currently (due to missing LXC Mantic images).

The "networkd-test.py" case is known flaky, but it might be worth doing some extra investigation before merging this, as it seems to fail in the PPA but not Mantic, currently (seems unrelated, though):
