Introduzione
Lo Slackware Chroot Environment AutoBuilder è uno script che permette di effettuare un'installazione della distribuzione Slackware GNU/Linux in un ambiente di chroot.
Per capire di questo script è necessario avere almeno conoscenze basilari sul chroot. Per avere informazioni al riguardo rimando a man chroot.
Vantaggi di un chroot rispetto ad una Macchina Virtuale
Molti usano le macchine virtuali per poter utilizzare due o più sistemi operativi contemporaneamente. Ma questo comporta notevoli cali prestazionali in quanto il Sistema Operativo ospitante (host) deve dividere le risorse hardware con i sistemi virtualizzati (guest). Con il chroot invece si ha la possibilità di eseguire più distribuzioni sulla stessa macchina senza perdita di prestazioni. Questo è utile se come me siete dei packager che usano una Slackware -current per l'uso quotidiano e devono avere una stabile full e pulita per i pacchetti. Questo script però è pensato anche per usi diversi dal packagement. Ad esempio, chi volesse usare Apache in un ambiente chiuso per ragioni di sicurezza può farlo tranquillamente utilizzando l'ambiente di chroot. Proprio per questo lo script vi da la possibilità di scegliere il tipo di installazione da effettuare.
Lo script
Requisiti
Per utilizzare lo script è necessario essere root ed avere almeno 7 GiB di spazio libero sulla vostra / (ovviamente lo spazio occupato sarà inferiore in quanto verrà successivamente eliminata la cache e inoltre lo spazio occupato varierà in base al tipo di installazione richiesta). È richiesto un emulatore di terminale dalle dimensioni minime di 80x24 (se usate la console di sistema non ci sono problemi).
Distribuzioni supportate
Lo script supporta solo Slackware Linux e può essere usato solo in ambiente Slackware. Le versioni ufficialmente supportate sono: 10.2 e successive, compresa -current. Supporta anche Slackware64 (tutte le versioni compresa -current) ---> NOTA: Il supporto a x86_64 non è stato testato, in quanto possiedo un i686, pertanto se avete una CPU 64 bit vi sarei grato se testaste questa funzionalità e inviaste i commenti nel topic: http://www.slacky.eu/forum/viewtopic.php?f=1&t=32951
