Dear Matthias,
the problem is not the basics. Sometimes my "phisiological hard disk" (my brain) is full and I write some basics questions to remember to myself basics concepts, and also to verify if in the last FreeBSD versions, some old unix concepts are just valid or only maintained for legacy.
I'm trying to transport my knowledges of Chorus unix like OS into FreeBSD and some concepts are different from FreeBSD.
This doesn't means that I need to begin from basics. Obviously I'm checking if some basics concept are the same and I can use them in the FreeBSD also.
Again. A question can have different replies, each of one can express different and valid interpretations of the same concept.
In any case I know who, in this forum has solid knowdleges at high level (sincerely I never had contacts with nor valid replies from lebarondemerde) and very strange is also the fact that every time I pose basics questions, I receive replies, but if I ask how to configure devfs.conf, devfs.rules and devd.conf ..... the replies seems vanish.
No problem ... when I finished to fix how to configure the access block of device nodes at run time, i'll write the solution, if you enjoy.
Founamentally, it is not so difficult ... I was only searching for someone in the forum that just have did it.
Regards.
Bye bye.
