This is a minimal self-hosting system for Docker containers, based on musl libc and BusyBox. It contains just enough to compile software, including itself.
Run the bootstrap script in the top-level directory of your working copy as follows:
./bootstrap.sh username
Where username is the username you wish to use for your Docker image tags. This will often be your username on docker.io.
This process produces the following images:
* username/muslbase: full self-hosting system (musl, BusyBox, and toolchain)
* username/muslbase-runtime: runtime-only system (no toolchain)
* username/muslbase-static-runtime: runtime-only system for statically linked programs (no toolchain or shared libraries)
