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