This will help troubleshooting, as the future sysadmins will connect to
the machine, run `journalctl -f ` to see what's wrong with the machine,
and in about 30 seconds they will see:

  Error fetching machine configuration!
  Error fetching machine info!
  If this is a new machine, did you add it into labmanager-admin?

So they will know what's wrong, and how to correct it.
