Stock udev already provides mapping according to actually useful identifiers (if the respective transport provides them: persistent and unique identifiers of targets and logical units). -- Stefan Richter -=====-==--= -=-- ==--- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
