Hmm, interesting point. 

But then again, those files are only updated during package
installation. OTOH machine-id is created on first boot (and probably
rightly so), and /lib is even less likely to be writable than /etc...

Also, Marc-Andre pointed me to the fact that the SSH server keys are
usually also generated at first boot and stored in /etc. Maybe we should
just treatthe machine id the same?
