It's a lot of things-free, to be fair

Chimera Linux actually uses apk or Alpine Package Keeper as its package manager, they acknowledge this but despite that market themselves as if they did something revolutionary that has never been done before

had the same thought, not sure if Alpine is built with LLVM though.

That's right ! It uses BusyBox as its userland which was my main problem with it (though you can easily install GNU coreutils).

Alpine is still GCC based in the very least.
