Thanks. I still cannot overview the exact/major imapct if it so does
only for a handful edge cases (your for ganeti beeing one) but we can
defintively keeping it as RC, thanks to you (and Rudolph Bott) for
reporting the issue.

Ack. I'm trying to check now with release team if we still should
cherry-pick the commit or going to just have to include it in the
first point release. it might be worth mentioning the known issue on
release though in the later case. If you have a good wording for that,
that would be welcome.

You are welcome, and feel sorry that a breakage was introduced that
late in the process for bookworm.
