I'm not very keen on the idea of every oe-core system having a tmpfs
on /etc/openssh just for read-only-root configurations where there
isn't a pre-generated key.

At least one better option would be to handle the read-only / with no
pre-generated keys situation in the init script, and write keys to
/run.
