Of course, because "devel-su usermod -a -G net_raw nemo" is such an obvious incantation

(I know what usermod does but have no idea what problem it is supposed to solve in this case and, by the looks of it, will never find out because svalx has deleted his/her/its post. People, please, do not delete your posts because "you found the solution"! That is the whole point: you ask, you get an answer, others can read the question and the answer and learn. If one side of the story is missing, no one can learn anything.)
