Hi,

Following up my request, I have subsequently discovered that using these
scripts to bring up an interface on a udev event is not reliable since
its liable to result in multiple ifup's running in parallel, and this
seems to be disallowed. So unless this restriction is lifted, it does
not seem useful to include these scripts.

Kind regards,
Antony.
