Alpine. It's wonderful. I've always liked minimal distros, and Alpine actively facilitates that. It doesn't get in the way, has everything needed to run a modern desktop, and the focus on security and musl compatibility are huge pluses.
I have read somewhere that some kind of port is being discussed, perhaps at Phoronix, but I cannot find it now. Maybe I have confused something, so I stand corrected.
systemd is indeed totally incompatible with musl libc.
