I am not going to garuntee a merge as this might be outside of the intent of the container.

But you need to keep packages in alphabetical order and make the same modifications to the Dockerfile.aarch64 and the Dockerfile.armhf arm variants of this image.,

Hi @vladimirvivien apologies for the wait.

We decided to add this as a docker mod, but had to figure out how to publish and host them first. There is now a mod for this at linuxserver/mods:openssh-server-openssh-client: https://github.com/linuxserver/docker-mods/tree/openssh-server-openssh-client

In your openssh-server container, set an environment variable DOCKER_MODS=linuxserver/mods:openssh-server-openssh-client and it will be installed during container start
