wsldl VS rootfs_builder

I generally recommend just DIYing your WSL distro: https://github.com/yuk7/wsldl

You can install a ton of distros for free: https://github.com/yuk7/wsldl

https://github.com/yuk7/wsldl combined with a tarball of the base root system (Gentoo is easy because that's how a system starts off anyway).

For installing the distribution we'll be using WSLDL, start by downloading the latest version of the Launcher.exe executable, rename it to your distribution's name of choice, such as oraclelinux.exe and place your created rootfs.tar.gz file beside it, move them into a directory where you want to install your WSL filesystem, and finish off by running the launcher executable we downloaded and renamed earlier, and.. you're done, the distribution is now installed into WSL and you can configure and setup everything as you need.

FWIW it's not too difficult to convert a docker image to a VM rootfs. See rootfs_builder[0] for example.

I'm currently working on a wrapper for QEMU that has docker-like semantics for pull/run/start/stop/exec/etc, but it will pull docker images from docker registries and convert them to qcow2 for you and run them in QEMU. It works on Linux and Windows and should work on MacOS and BSD eventually.

After go has finished installing you're going to want to clone this repository and build the executable, this tool will allow us to extract the root filesystem from the docker image into a directory of our choosing.
