funny, now you see my discarded attempt at anonymizing the user, because copy+paste sucks.
I'm sorry for the excess content caused by this. Shouldn't have tried anyway.
I didn't find a cause of the system migrate requirement yet, but a workaround that at
least keeps the automation running: User cron job that checks every minute if podman
responds with the "system migrate" requirement, and if so, execution of podman
system migrate.
