Debian doesn't by default (you can use systemd or upstart, but sysvinit is the 
default init system). Probably others, as well as *BSDs (some people are 
interested in porting wayland to them).

While it would be nice if sysvinit et al supported XDG_RUNTIME_DIR, and even 
though I plan on switching to systemd, wayland is still not following the spec.
