Thanks for the smart question, I know the answer for some of them but I realised I have to do further investigation on regarding my system needs. Regarding the Step 1 : where do you usually find specs ? There is somethings like RFC for filesystem ? needed_specs=$() ? :-) Thanks Pietro. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
