Ugh, that explains a few things I've seen. Cases where that breaks:

  1) Installer

You can set up the installer with ssh installation. That spawns sshd in the 
instsys, so you can install a system headlessly. But only the root user exists, 
so you can not log in anymore.

  2) The same applies to the dvd rescue system.

  3) JeOS

Our images define a root user only by default, so you can not install JeOS 
images headlessly anymore
