# protocol
I have a problem when I run @world update since gentoo-sources is in my world file it update my kernel but does not compile it and it fuck up portage especially to compile nvidia

1st: delete gentoo-source from world and treat it like portage
aka: emerge -1

2nd: choose a lts kernel every update

# add build & symlink useflag ? post-hook prefered ?




# post install hook

0- must know before updating what change have been made

1- take care of symlink with useflag so every new updated of gentoo-sources point to most recent kernel
su

make mrproper ??
make olddefconf ??

make -j$(nproc) && make modules_install install
