Gentoo Cheat Sheet

Use flags are in the USE variable located at /etc/portage/make.conf.

After changing the USE flags, use this command to recompile all the packages to reflect the new flags:

emerge --update --newuse --deep --quiet @world

• You'll want to cd to /usr/src/linux-<version>-gentoo
• Run make menuconfig to configure your kernel
• Run make -j$TC && make -j$TC moddules_install && make install (where $TC is the thread count, i.e. the number of cores in your CPU+1)
• Update grub with grub-mkconfig -o /boot/grub/grub.cfg
• Lastly, use genkernel initramfs to update your initramfs
