Comment:
@zippy2 fyi it's not creative interpretation, it's intentional because there's no way you can implement those functions sanely in a library - it's in their FAQ after all, you need an external process to implement them properly (the musl developers think a setuid executable because they are writing a libc, so all they need is to install /usr/local/bin/musl-utmp, ska prefers a daemon because he's writing a supervision suite + init).

There was even an article on hacker news a few months ago detailing in which ways these functions were broken on the various unices and how nobody cared enough to fix them; the only reasons I personally care (a little bit) are w(1) and "last login on $date", which are both broken on a musl-based distro.
