 The list was easy to find; what I could not find was
 any indication of how/where bugs should be reported.

 As an FYI, in our current embedded systems (plural),
 a static /dev is used (no udev, mdev, &tc).  Hence,
 udev (and I assume also, devfs) path may not work
 in such an environment?

 I don't know if it is exportable or not, but I concur
 this seems like a possible/plausible solution.
