[rsyslog] How to write to a local socket?

[Ryan Lynch]

I just configured a privilege-separated RSyslog instance, and it's
running fine. To read the kernel message log, I'm running a second
daemon instance as root, along the lines described in the wiki.

Currently, my root instance forwards messages via UDP to unprivileged
instance's localhost-only listener. It works, but I'm not entirely
happy with it.

I'd like to forward via a local UNIX domain socket, instead. I think I
understand how to configure the 'imuxsock' module so my unprivileged
instance reads from a non-standard socket location. But I can't figure
out how to tell my root instance to forward via a local domain socket.

Is this possible? If so, how?
