# We need a hardware independent 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
