No problem, I'm going there every week and can do as much testing as 
necessary even if it takes months. We got a donation of a standard PC so 
we have now one publicly usable PC at the library.
So I can take my time to try to make something out of the iMacs.

Results:
- 2023-06-18: ok
   - running strings on iso's vmlinuz yields 6.3.7-1 (2023-06-12)
- 2023-11-16: fail
   - 6.5.10-1 (2023-11-03)

As expected, the regression happened during the big gap between 
snapshots >_<

Anything more I can test?
(cross compiling old kernels is unfortunately too much over my head)

It's weird that it seems the regression is about booting the iso. 
Otherwise, net installs from old iso like what Claudia did wouldn't work 
after rebooting after install.

Cheers,
