This is a mini-HowTo on running Finit in an LXC system container. We will be using a variant (external) of Buildroot, called NetBox to create a squashfs (read-only) image for the root filesystem. Then we will give the container a single writable directory from which it then uses bind mount to emulate a full-blown system. It is expected you have LXC installed and all the relevant build tools needed to create the image. How to set that up is not covered by this tutorial.
