Configurando o OpenRC Logging

   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

rc-update add sshd default  

rc-update add cronie default  

rc-update add dhcpcd default
