Comment 6 for bug 1839290

Mathew, I've just checked the ubuntu-disco branch of systemd — it looks like fix was backported in systemd=240-6ubuntu5 with a bunch of other fixes, see debian/patches/Change-job-mode-of-manager-triggered-restarts-to-JOB_REPL.patch. So disco was fixed before this bug was actually filed.

Xenial and Bionic are still affected — any chance of a bugfix landing there?
