I wish to thank you for your patience, believe me if i ask so many questions its just because i have gone trough about 15 years of absolutely indescribable chaos, a low quality and ugly commercial OS experience, in which editing a file sometimes means nothing, sometimes produces random effect or a complete loss of all data, and running executable is a real adventure - you never know what will happen.
After that i have still difficulties to not be afraid of modifying the files or running the scripts.
Finally i decided to run build-magic.sh again, then i checked magic.conf, and i understood all i was asking about
