Eu escrevi um pequeno script bash uma vez que pega um ISO do Arch Linux e gera um novo ISO com uma imagem raiz modificada que faz uma instalação totalmente automatizada. Isso inclui particionamento, além de instalar e configurar o sistema com Xorg, FVWM e Chromium. O sistema instalado fará login automaticamente e iniciará o Chromium. Basta colocar o novo ISO em uma unidade flash USB e recuar. ;-)
Isenção de responsabilidade: o script é fornecido como está, sem garantia. Eu não o uso há algum tempo, por isso pode precisar de um ajuste aqui ou ali. Modifique conforme necessário.
