Comment 16 for bug 1761096

On Xenial the source package is squid3, not squid, so I'll add/adjust tasks for that so the tracking works correctly.

On Bionic the code suggests that the same problem might exist, but it appears that nobody has reproduced it there so there is no need for an SRU to Bionic. However, if somebody is affected then we can look again. I'll leave an Incomplete task for Bionic to try to highlight that. We don't have any specific policy or pattern to track this kind of thing so I'm being inventive with the bug status here.

Excerpts from #ubuntu-devel:

17:32 <rbasak> cpaelzer, sergiodj: in bug 1761096, did you ever find out why Bionic are unaffected, or did you decide it wasn't worth investigating further?

17:32 <rbasak> *is*

17:38 <sergiodj> rbasak: we could not find exactly why Bionic is not affected. my hypothesis is that between Xenial and Bionic there was a fix on systemd which addressed this issue, but I could not pinpoint exactly what was done

17:39 <sergiodj> arguably, the best scenario would be to backport this fix to Xenial's systemd, but since we had already spent a non-trivial amount of time investigating this (without finding anything concrete on systemd's side), I opted for the second best thing to do, which is to use --no-block to workaround this bug
