I don't have tree. I replaced fileutils and others with coreutils; perhaps
there was an oversight. Will have to hunt for it.
But I battled on with /proc, /sys, and find. I found where the files are,
but udevinfo (and presumably udev itself) rejects that path. It's all in
the attached file - please have a look.
Thanks,
Bob
