using debian dvd iso image with apt

[Raffaele Morelli <raffaele.morelli@gmail.com>]

Hi you all,

I have 3 debian boxes (two i386 and one amd64) which are not connected to the network so I usually do upgrades by downloading weekly generated dvd iso images, burning images to a dvd-rw and running apt-cdrom add && apt-upgrade.

My question is: can I fool apt in order to avoid burning dvd-rw each week?

I am not lazy but I do this regularly and burning two dvd-iso for different archs sometimes makes me crazy because of errors, dvd's failures or data corruption.

Any suggestion is appreciated.

regards
