Hace unos meses escribí un post que resultó ser bastante concurrido acerca de como compilar el kernel en Ubuntu. Se me olvidó entonces añadir un paso que, aunque no es obligatorio, es bastante recomendable antes de proceder a la compilación (por motivos religiosos y tal): Justo despues de:
sudo apt-get install linux-source
cd /usr/src
tar xjf linux-source-2.6.xx.tar.bz2
#sustituir xx por la version de tu kernel (que hay que decirlo todo (dios mio))
Hay que escribir:
grep -r fuck linux-source-2.6.xx
Y deleitarse un rato con la lectura. Se recomienda al lector probar también con otras palabras malsonantes. Aquí tenéis un ejemplo del resultado:
linux-source-2.6.24/net/ipv4/netfilter/nf_nat_snmp_basic.c: * (And this is the fucking ‘basic’ method).
