 Trying to fix full boot partition which failed to install new kernel rpm properly by: (Wrong solution, see end of chapter!)

 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.

+Calculate sha256 of all files in folder and store in text file that can be used to check for bit rot later or when replacing disk and checking rsync:

+  or
+  $ find movies/ -type f | sort | xargs -d'\n' sha256sum >checksum.txt
+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.

 After upgrade:
+  - For fedora 39 there is a bug when installing kernels fails with "No space left on device" if you have upgraded since really old fedora versions. There is a file/folder in /boot that triggers this issue. See end of "efi partition too small" chapter.
   - It hangs during first boot waiting for lvm2 mirrors. I had to disable Intel RST and use AHCI in BIOS to get it to boot. Then I disabled/masked the lvm2 service using "systemctl mask lvm2-monitor.service" and switched back to RST in the next boot.
   - Old, not be needed anymore: It is running cgroups v2 which was incompatible with docker. Either switch to v1 using kernel command line options or use podman instead of docker. Add "systemd.unified_cgroup_hierarchy=0" to GRUB_CMDLINE_LINUX in /etc/default/grub and run "grub2-mkconfig" to start using v1 again. You will probably want to upgrade to podman later though and start using new cgroups.
   - Had to upgrade to squeezeboxserver 7.9.3 and build tbs with workarounds for kernel 5.7. Later I replaced tbs with a hauppauge dongle.
   - New samba 4.11 disables smbv1 by default which does not work with my tablet used as a photo frame. See samba section above for how to fix.
-  - Autologin had to be reconfigured in /etc/lxdm/lxdm.conf for fedora 37.
+  - Autologin had to be reconfigured in /etc/lxdm/lxdm.conf for fedora 37 AND fedora 40. Just add back the autologin line, see the .rpmsave file.
   - Maybe clean up old unmaintained packages using "remove-retired-packages 36" or similar. You may also use "dnf repoquery --unsatisfied" and "dnf repoquery --duplicates" to check for broken/duplicates. See fedora upgrade docs for more info.
