Most of the time atleast. Things like hotplug can change the order of
the devices and thusly the numbering.

But that's kind of rare and most of the time the devices will be
installed at boot time. We also know what algorithm the kernel uses,
so it should be relatively easy to match what the user expects in most
common scenarios.
