Las fuentes

Vamos a instalar la versión de desarrollo.

Nos vamos a crear nuestro sistema en otra partición, sino que directamente creamos el directorio:
mkdir /lfs

Exportamos la variable de entorno que nos indica donde está nuestro lfs:
export LFS=/lfs

Creamos los directorios para las fuentes:
mkdir -v $LFS/sources
chmod -v a+wt $LFS/sources

Y nos bajamos las fuentes y parches, para ello creamos un script:

#!/bin/bash

Nosotros el sistema de ficheros que vamos a utilizar es ReiserFS, por tanto nos bajamos el fuente: http://ftp.namesys.com/pub/reiserfsprogs/reiserfsprogs-3.6.19.tar.gz

A partir de aquí seguir las instrucciones.
