After playing with your code, I came up with an Alpine image for fun. I'm going to use a variation of it for the game server I'm running with my friends. I didn't want to create a PR or anything unless you were interested in it. As such, I'm just going to share the gist of it below.

cp ./serverconfig-default.txt /config/serverconfig.txt

Note, in my rendition, you can pass in whatever arguments you want to the container and it will respect them. In this case, rather than using the CMD defined inside the Dockerfile, it's using what I passed in. The effect of the command above is that there is no banlist used.
If you're not interested, no worries. I personally don't want to maintain a repository for this, so I thought it would be nice to at least put it up somewhere where others might be able to see it, and since this code is largely influenced by your work, I figured this was the best place. :+1:
