Debian: produzione di CD, DVD e BD.

con una e-mail al debian-cd@lists.debian.org, Steve McIntyre <steve@einval.com>, fa il punto della situazione per quanto riguarda la disponibilità di debian per il download alle varie architetture. Sicuramente apprezzabile la possibilità di scaricare un immagine per il Blu-ray disk (25 Gb), dove, in un solo disco si dispone di tutto quello che Debian mette a disposizione per un'architettura. Riporto di seguito l'e-mail completa:
