I admit my setup isn't really the most common for production, but for the home lab crowd it might be ok. Realtek makes many network chip models I assume and their implementation might also vary from board manufacturer to another.
About not using VMware - that's a tougher ask :)

As stated, building libvyosconfig outside of the Docker image may not be desirable. However, as a compromise solution, we can consider moving the vyos1x-config pin/build into the libvyosconfig build script. Suggested PR to follow, and update to task description.
