Yeah, on some fundamental level.
Most linux distros would be very moddable repairable off-the-shelf cars. LFS would be your diy project with various guides. And gentoo would be a parts garage with their own guides and precompiled kits of components, so you can either follow those sets and build a more off-the-shelf car or diverge at any point for any section and run wild. But also you can still use the machine shop of the store and they offer to custom build some consumables for you and keep shipping them.
