Esiste un bug segnalato da molto tempo (267838, segnato come bug che non verrà risolto) riguardandte l'installatore Debian che riguarda la possibilità di avviare una macchina usando DHCP durante l'installazione, ma creare il sistema installato con una configurazione di rete statica.
Questo è uno script scritto da AlexOwen da eseguire al primo avvio per fare il cambiamento per conto dell'utente. Accetta anche un argomento "--bond" per la conversione in un'interfaccia statica bonded.
L'autore lo rende disponibile nella speranza che sia di aiuto ad altri.
