This is strange, it definitely works on my Debian with
--foreground. No matter, you're right that setsid shouldn't
be called when in foreground, I'll fix that.

Ok, I see the problem with systemd.

I'll go over the daemon requirements for systemd and make
sure you have options to satisfy them (except the "grab a
name on the bus", I don't think sslh needs to get into
that).
