 Eventually I found https://www.reddit.com/r/Fedora/comments/186amfb/kernels_6510_does_not_install_properly_in_fedora/ and https://discussion.fedoraproject.org/t/f39-kernels-fail-to-install-when-boot-efi-machineid-is-present/96086 which apparently was a fedora 39 problem when upgrading since forever. The solution was:
   # mv "/boot/efi/$(cat /etc/machine-id)" "/boot/efi/$(cat /etc/machine-id)_disabled"
+I deleted the _disabled folder later to get back some disk storage. Seemed to boot fine, but it was the rescue stuff that was taking disk space.

 There was a period when the community squeeze project had a fedora repo available. This is no longer the case, but there are still some nice guys updating the server:

+File checksum mismatch after copying files to a new disk can be due to memory issues. It can even vary checksumming the same file on the same disk. You can use "memtester" live in linux or reboot into memtest in the grub menu. In my case one of the two pairs/kits were faulty I eventually found out after removing/swapping pairs.

 Seems ok. Had to do this later for "events" as well. Do not forget to remove the recovery setting and restart mariadb so that home assistant can connect. Moved away from remote mariadb hass database to the default sqlite implementation with a database on an ssd. Set up a nightly backup through an automation to to avoid all these issues. Seems quicker as well.

 You may need the "--allowerasing" flag or possibly force uninstall of some packages using "rpm -e --nodeps <package>" to get this to pass.
