It would be convenient to allow updates of the vyos-1x dependency, libvyosconfig (and its dependency vyos1x-config), without updates to the Dockerfile. This can be done for the package libvyosconfig itself; it remains to set up installing the dependency for vyos-1x when building the latter. Note that the various libraries supporting the vyos1x-config build should remain in the Docker image, as they are updated rarely.
