Configurando o OpenRC Logging

nano -w /etc/rc.conf
   rc_parallel="YES"

Se estiver instalando em um ssd

nano -w /etc/profile.d/xdg_cache_home
   export XDG_CACHE_HOME="/tmp/${USER}/.cache"

Instalando firmware

emerge --ask sys-kernel/linux-firmware

Informação de host e domínio

nano -w /etc/conf.d/hostname
   hostname="gentoo"

Configurando a rede

Primeiro instale o pacote net-misc/netifrc

emerge --ask --noreplace net-misc/netifrc

Iniciando automaticamente a rede durante o boot precisam ser criados assim como fizemos com o net.eth0.
Se após a inicialização do sistema descobrirmos que o nome que usamos para a interface de rede (que está atualmente documentada como eth0) está errado, então execute os seguintes passos para corrigir isso:
1.Corrija o arquivo /etc/conf.d/net com o nome correto da interface de rede (tal como enp0s3 em vez de eth0).
2.Crie um novo link simbólico (como /etc/init.d/net.enp0s3).
3.Remova o link simbólico antigo (rm /etc/init.d/net.eth0).
4.Adicione o novo ao runlevel default.
5.Remova o antigo usando rc-update del net.eth0 default.

cd /etc/init.d  
ln -s net.lo net.enp0s3  
rc-update add net.enp0s3 default  
cd /

O arquivo hosts

Adicione um nome depois de localhost

nano -w /etc/hosts  
   127.0.0.1 gentoo.homenetwork localhost

Adicionando senha para o root

passwd

Teclado

nano -w /etc/conf.d/keymaps  
   keymap="br-abnt2"

Hora local.

nano -w /etc/conf.d/hwclock  

   clock="UTC"

Sistema de log

emerge -aq sysklogd cronie mlocate logrotate dhcpcd  
rc-update add sysklogd default  
rc-update add sshd default  
rc-update add cronie default  
rc-update add dhcpcd default

Selecionando/Instalando um gerenciador de boot: GRUB2.

Obs: Cuidado no "grub.cfg" pois ao aperta tab ele altomaticamente coloca "grub.conf".

Modo BIOS

emerge --ask sys-boot/grub  
grub-install /dev/sda  
grub-mkconfig -o /boot/grub/grub.cfg

Verifique se a partição do EFI/boot esta criada/montada

Modo UEFI

mkdir -p /boot/efi Verifique antes  
mount /dev/sda1 /boot/efi Verifique antes  
mount -o remount,rw /boot/efi  
echo 'sys-boot/grub:2 mount truetype' >> /etc/portage/package.use/grub:2  
emerge --ask --update --newuse --deep --verbose sys-boot/grub:2  
mount -o remount,rw /sys/firmware/efi/efivars  
grub-install --target=x86_64-efi --efi-directory=/boot/efi --removable  
nano -w /etc/default/grub
   GRUB_TIMEOUT=1
grub-mkconfig -o /boot/grub/grub.cfg

Adicionando um usuário e senha

useradd -m -G users,wheel,audio,video,root,sys,disk,adm,bin,daemon,portage,console,usb,cron,input,lp,uucp -s /bin/bash nomeUsuario 
passwd nomeUsuario

Saindo do sistema

exit  
cd  
umount -l /mnt/gentoo/dev{/shm,/pts,}  
umount -R /mnt/gentoo  
shutdown -r now
