Comment 27 for bug 1874719

It's unfortunate that corosync in Focal behaves differently from the other Ubuntu releases regarding the default node name. We think that changing it back via an SRU is not worth it after all this time since the release:
- it's a change in behavior in an LTS release in a default install
- it would incur in annoying dpkg config prompts for all users who have clusters installed and configured
- the hacluster charm, which was impacted by this, was changed to accommodate the current behavior of corosync (but would still work if we changed it again)

Therefore I'm marking the focal task as wontfix.
