This fixes https://github.com/snapcore/core-initrd/issues/33. Tested by building a core20 snap from focal proposed.

So the OnFailure settings are ignored for targets (see https://github.com/snapcore/core-initrd/issues/33 for details). Upstream fixed the issue in v246: https://github.com/systemd/systemd/commit/94d1ddbd7cd15b1073757eb5ae0645c83f0b414c [Test Plan] Test on a UC system and check that the above warnings are not shown anymore. Check that when a target service type fails, the OnFailure setting is used and the mentioned service is run. [Where problems could occur] Issues might happen if some target has an OnFailure setting that was never run in the past because of this bug, and the behavior is not really right because it was never tested. However, OnFailure is not used that much on 20.04 in target services: /lib/systemd $ find . -name \*.target | xargs grep OnFailure /lib/systemd $ /etc/systemd $ find . -name \*.target | xargs grep OnFailure /etc/systemd $ I've seen it only in emergency.target for UC20.
