Yes, this doesn't work right now, as the Linux kernel prohibits open()
on sockets, and systemd's service management connects stdout/stderr to
an AF_UNIX/SOCK_STREAM socket, and open("/dev/stdout") hence will
fail. There have been ideas how to fix that, and replace the socket by
a pipe, which would make this work, however so far nobody started
working on that. (patches very welcome!)
You could use a fifo in the file system as workound. Connect one side
to your app, and the other one to systemd-cat, and things should
work. But it isn't precisely pretty...
Sorry I don't have any better suggestion for you right now.
