  Thank you so much mate.

This kind of shared experience was what I was looking to hear to know… to see them…

Cheers!

I used sometime ago, but it caused me the fact of not being able to upgrade my systems weekly or daily, because sometimes you needed to upgrade the kernel and I was not really sure that the config entered for the kernel (loaded through Genkernel but with menuconfig and there load .config file) that was written with previous kernel version building was going to not cause something weird or bad functioning of newer built kernels with that config.
