For those interested in reproducing the issues experienced on Alpine, I've
published an image that you should be able to start with:

$ docker run -ti brianmhunt/context-alpine:demo

(You can see the Dockerfile etc here:
https://hub.docker.com/r/brianmhunt/context-alpine/)

That image applies the TODO/workarounds previously posted (sometimes
inelegantly) and brings it to the point where I got stuck, namely luatools
and context erroring with "unknown script base.lua" and "unknown script
context.lua", respectively.
