Installation d'une Gentoo

Pour l'installation d'une machine Gentoo, il faut suivre le handbook officiel. Cette page ne continents que des bouts de configuration visant à simplifier l'installation.

Vous trouverez dans cette page quelques snippets utile pour la configuration de la machine durant son installation. Il faut viser une installation minimale, puisqu'elle ne servira qu'à bootstraper Puppet, qui appliquera tout le nécessaire à Grifon lors de son exécution.

post-chroot:

Configurer le hostname et renseigner le FQDN dans /etc/hosts

echo tux > /etc/hostname

Configurer le network via netifrc:

emerge --noreplace net-misc/netifrc
vim /etc/conf.d/net
cd /etc/init.d
ln -s net.lo net.eth0
rc-update add net.eth0 default

Configurer le password root: passwd
