Ik zou pas met debian packages beginnen te werken als je de software op
meerdere plekken wilt installeren en onderhouden. Op deze manier kan je
dan ook zelf een eigen debian repository opzetten en eventuele updates
op deze manier uit rollen. Volgens mij is een makkelijkere manier om je
django website te deployen via bijvoorbeeld SVN. Je doet een checkout
van een tag of de trunk op je productiesysteem.

De django website zelf staat ook in de svn, volgens mij checken ze deze
uit op een ontwikkelmachine en doen wat ontwikkeling, committen naar
svn, testen op test machine en daarna checkout op productie. Django is
flexibel genoeg om dit alleen met deze acties je website te kunnen deployen.

Kortom; packages zijn mooi, maar om alles in een package te stoppen is
een beetje overdreven.
