All About Ubuntu Flavor Development

What Makes Up A Ubuntu Flavor Operative System?

The Flavor Meta

The flavor meta source is a single package source, which, when built, may result in a multitude of binary meta packages. The metas themselves are always empty, but depends on a set of packages, which form what you could call a package set - the list of packages that make up that flavor.

Special Packages

At the very least, each flavor will have a package called <flavor>-default-settings. This is not an empty package, like the meta, and includes some specific system settings for that flavor.

Some flavors will have additional special packages, such as theming packages, or flavor specific applications.
