When my potato boots it warns me of a modprobe problem (char-major-10-135). I've tried to modify modules.conf putting an "off " at the end of the relating line. It works for some boot but "a thing" (I know that in debian potato "it" exists, but I cannot figure out where/what to manipulate!!) changes automagically my hand settings and restores the previous situation. How can I permanently modify a configuration file? Vittorio
