# We need a hardware independant way to identify network devices. We
# use the /sys/subsystem path for this. Current vanilla kernels don't
# actually support that hierarchy right now, however upcoming kernels
# will. HAL and udev internally support /sys/subsystem already, hence
# it should be safe to use this here, too. This is mostly just an
# identification string for systemd, so whether the path actually is
# accessible or not does not matter as long as it is unique and in the
# filesystem namespace.
