Hello Pierre, I was so curious with regards to the various options available, that I took the time and did a google search, which brought up the "help" file at kernel.org: https://www.kernel.org/doc/makehelp.txt There are options that I have never even explored before. I guess that I am going to look at making use of the listnewconfig and allyesconfig in the future.
