Every container started with this image has the same key

RUN ssh-keygen -A

Are you sure you don't want to do this conditionally in start.sh? With this, every container created with this image will have the same ssh host key which is bad.

and recreating the docker container also means that the host keys are regenerated, since they are not exposed in volume to make them persistent.

Seems like it can be easily modified to move the host keys to /etc/ssh/host_keys and have the option to mount it as a volume. If the files don't exist, generate them, else leave them alone. I'm in the process of doing this with my fork.
