Could you clarify how this affects/changes behaviour for distros not 
running systemd?

Also, I personally don't like the idea of saving the mixer state at 
shutdown. (Although I know Ubuntu has that as well.) Too many times I 
have cranked up the volume for some reason, then turned the computer 
off, only to find the login sound at maximum volume.

That assumption is not necessarily true at this point. AFAIK, it remains 
to be seen. That said, I don't mind a systemd patch into alsa-utils, as 
long as it doesn't break or bloat anything for non-systemd distros.
