Note that such a convention is already the default in upstream udev [1]
(at least assuming the hardware layout on the machines is the same - if
it isn't, then it's of course impossible to have any non-site-specific
rule which could determine which parts of different hardware layouts
should correspond to each other). The udev packages in experimental
support that naming scheme, but as a Debian-specific change still
default to the old naming rules (the ones that modify configuration when
they see a new MAC address for the first time).
