Look a few lines higher, it is recovering the filesystem. All of our
shutdowns are unclean because of #9629

This is because our SD write performance is terrible (#9688) and at
least for me this is nothing new. If you think otherwise it would be
good if you could downgrade to an OS that you think didn't have these
problems and confirm it.

This is because we enabled fedora's temporary state feature for the
tmpfs mounts and so on.
