I'm doing this as well, (Wanting to make a from scratch version of CoreOS). From what I have researched you can do a couple of things. - Could start with something like buildroot / Yocto project. Both projects have lots of archs. Buildroot would prolly be easy to bootstrap your OS. - Use something like Gentoo, Void, Alpine Linux. These distros have pretty good community support but you might be a little bit hard getting stuff started as you would have to set everything up using their tooling. - Look at Cross Linux From Scratch as it will probably help you will with bootstrapping your OS for your specific Arch.
