No, but anyway I don't see any real use case for that program at all. You have
all the random hotplug event order and the bad sysfs timing problems which is
definitely not what you want to have in a "next generation"-hotplug. :)

And with your proposed $DEVALIAS changes the hotplug-ng gets so small that it
may be easier for it to live in the udev tree?

Sounds good to me. We may change the suffix parameter to accept a match
string instead? And we change this function to return a sorted list of files
which are matching.

Hmm, I prefer the first one.
