Compile

Descrizione

Questo script effettua le operazioni necessarie alla ricompilazione del kernel dopo aver configurato lo stesso tramite make munuconfig. Va eseguito dalla cartella /usr/src/linux. Compila e installa kernel e moduli, elimina i vecchi file in /boot e vi mette quelli nuovi, lancia lilo quando ha finito
