I wanted my example to fit on a single line...
Seriously, though, there are merits to something like the Solaris /devices
and /dev distinction between physical and logical device names (though they
still kept the SysV brain damaged /dev names).
I don't see a particular need for seperate /devices and /dev directories
(unless it simplifies the implementation), but I can envisage /dev/da0a
and so on simply being symlinks to device names which encode more of the
physical device heirarchy.
/dev/da0a -> da0s4a -> ahc0/bus0/target0/lun0/...
Cheers,
Mark.
