Debian has thousands of packages in the official repo, so it is possible to download 5 blu-ray discs then merge the ISOs into a single ~90gb ISO containing all apps. From there, that disk can be used to install apps at any moment without Internet access.

Then when Debian moves to a new release, it’s possible to go to a public library and fetch only apps that changed because jigdo can use the previous disk to build the new ISOs.

Apparently Ubuntu and Fedora both also have the same jigdo capability. Is that all? Are there any other distros that:

  1. have a good number of officially supported apps, and
  2. have a download manager that can build a full release using the previous release

?

I am assuming jigdo is the only game in town, and that without a *.jigdo file we can only fetch whole new set of images when a new version is released. Correct?

There's systemd.offline-updates as well. Guess several other distros which support that, can, or could do offline updates as well. For example there's pacman-offline for Arch.
