But devkmsg ratelimits systemd errors, so one does not even know that "some debugging is required". For instance from my x86 box: Unmounting /home... [..] home.mount: Mount process exited, code=exited status=32 Failed unmounting /home. I don't want to debug systemd, I want to know that something didn't work out. 10 messages max and 5 seconds interval looks a bit too strict. -ss
