When debug-tweaks is not in IMAGE_FEATURES, there is no valid password set for 
root, i.e. the account is effectively locked.

One way to do it would be to define a shell function in your image recipe (or a 
class that your image recipes all inherit, if you have more than one) that 
modifies ${IMAGE_ROOTFS}/etc/passwd, and then add that function to 
ROOTFS_POSTPROCESS_COMMAND.

Cheers,
Paul
