Thanks! Where can I read more about that? I looked at musl's website, but didn't see any mention of standalone binaries on the page comparing it to glibc. [0]
This is more of a Rust quirk[1] than a glibc/musl thing. Glibc can be used statically (though it's not really recommended -- hence why Rust doesn't support it and requires you to use musl instead).
