So this means you need either Alpine repos or compile everything yourself?
Void offers musl too. Unless they’ve discontinued it.
But
compile everything yourself?
I do (almost) exactly that. I run Gentoo almost everywhere. The ‘almost’ is because Gentoo now offers an official bin repository too, so I can mix compiled and pre-compiled software. (Although you’ve always had the option to set up your own binary host).
How are you going to run steam though? Like at least alpine has wine, but there’s no way to recompile steam unfortunately.
