Er, unless I'm missing something about what you're adding in the other patch, 
you *cannot* simply remove this. The intentional design of the existing code 
is that having "debug-tweaks" in IMAGE_FEATURES means that you can log in as 
root with no password; but most importantly if "debug-tweaks" is not present 
you cannot log in at all as root (in the absence of anything that sets the 
root password, of course). Any changes must preserve this behaviour.

Cheers,
Paul
