I was really just thinking of this:

  lrwxrwxrwx 1 root root 12 2005-05-11 13:00 /proc/device-tree/pci -> pci@f0000000

It's true that working out the proper path to compare against involves more
code. However, I already added Pegasos support to ofpath, so we could use that.

If it's necessary to do 2.6ish things in Debian they can always be guarded by a
simple test.
