Xtra packages on Custom CD

[Douglas Alves]

Hi Commoners (members of the community),

I have several PCs off-line which I wish to update with language locales
& some extra software from the repos. My main PC, which has internet,
has just spent 8 hours upgrading 1400+ packages to Breezy, and I want to
put those new packages on CD(s) to upgrade my disconnected PCs.

Where are the downloaded packages stored?

Would it just be a question of making an .iso of these packages and burn
it on a CD?
