How To Use Jigdo For Incremental CD Updates (Daily Builds)
Jigdo is really nice for rebuilding daily CD images without downloading the entire CD again, which can waste bandwidth and time when the latest daily build may have only updated a handful of packages. Here is what you’ll need to setup and use Jigdo.
The first thing you’ll need to do is install the needed jigdo packages.
sudo aptitude install jigit jigdo jigdo-file
It should be noted that Jigdo is a console based application so if you’re afraid of the terminal it might not be the best for you… but I suppose if that were the case you might not be downloading daily builds for testing either.
