Yes, this is indeed the case. The path we execute must be a real
path. There's a bug open in rhbz to support env vars for that too, but I
am not sure this is really advisable, as this would make correct selinux
labeling of sockets on socket activation very fragile (i.e. we douln't
just query the db for the right label based on the exe path, since we
wouldn't know it that early).

So I am tempted to just say this is not supported and document this.
