That’s it ! The newbie (maybe not anymore) has succeeded thanks to the script provided by Harvey 
I will now work on a howto, and try to make it THE ultimate howto to build /e/, especially for newbie, based on what is available on this forum. Could be released in 2 weeks, or 1 month, I don’t know.
Thank you everyone, I didn’t think I would get so much help when I wrote this topic
