doesn't work without systemd

[shithubsucks]

This software assumes systemd and doesn't work without it.

I've managed to get it running by manually coping the files into if-down.d and if-up.d, setting up /etc/default/clatd, and then in a root interactive terminal manually invoking clatd. This seems to start the tun interface just fine.

Why is systemd a dependency to make this work? I don't see how that is actually needed here.
