Code review comment for ubuntu/+source/openipmi:paelzer-lp-issue-workaround-temp-namespace/2.0.27-and-init-for-focal

This has a new upstream for a year now.
Furthermore I found an open bug that is valid.

Fixed both and ready for upload going ahead of Debian for now.
PPA: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3848

It is in bileto, but has no reasonable tests that are worth to link here.

P.S. Debian has no git to MR somewhere, but I'm planning to submit a debdiff to a new bug once we are ok with this.
