A good starting point is to look at the ExecStart lines in the udev
service files used by systemd. You'll likely want to pass --daemon to
the main daemon though so that it will fork to the background:

http://cgit.freedesktop.org/systemd/systemd/tree/units/systemd-udevd.service.in
http://cgit.freedesktop.org/systemd/systemd/tree/units/systemd-udev-trigger.service.in
http://cgit.freedesktop.org/systemd/systemd/tree/units/systemd-udev-settle.service.in

(note that the order matters).

Apart from that I don't think anyone is using/testing/developing for
this setup any longer, so you are mostly on your own, sorry.

HTH,

Tom
