In precedenza, tale livello di supporto era stato fornito per i sistemi a 64 bit x86 (fino a poco tempo fa, anche l'architettura i386 era primaria, ma a gennaio \u00e8 stata retrocessa al secondo livello di supporto).    <\/p>\n<p>Il primo livello di supporto implica la creazione di pacchetti di installazione, aggiornamenti binari e pacchetti pronti all'uso, nonch\u00e9 la garanzia di risolvere problemi specifici e mantenere l'ABI invariato per l'ambiente utente e il kernel (tranne per alcune sottosistemi).
