GNU/Linux distributions integration is not intended to follow all requirements for native packages and in most cases cannot be reused for distribution official repositories. There are only three major ideas behind distribution support:
 
−
* run Zero package in particular GNU/Linux distribution using native packaging system
 
−
* do not interfere with official packages
 
−
* make packages reusable for 0install deployment model

Zero Sugar is designed to support primarily [http://build.opensuse.org/ OBS] workflow. Each OBS package is an all-sufficient Zero Sugar entity (with one exception, it knows nothing about 0install infrastructure) i.e. it could be used as meta packaging tool (at least within [http://wiki.opensuse.org/openSUSE:Build_Service_supported_build_targets distributions] that OBS supports). It is possible to follow regular OBS procedures for these Zero packages e.g. creating links to Zero packages and branching them within OBS.

# do not reinvent the wheel by implementing packaging related features in sugar. For example, for now, sugar manages what activities (i.e. packages) should be launched, from native packages in /usr or from ~/Activities, or sugar supports versioning scheme for activities (simple version numbers vs. dotted versions) or sugar supports MANIFEST files with not yet implemented hashes. All these are regular packaging procedures and it is already implemented. The idea is to reuse 0install as packaging "engine" keeping in mind that:

## its decentralized nature, sugar is all about (re)creating activities that should be some how distributed, using only distributors channels decrease sugar values
 +
## it supports all existed GNU/Linux distribution efforts e.g. there is no need to repackage already packaged, by distros, software, 0install will use PackageKit to install it

Summary

The GNU/Linux distributions integration feature of Zero Sugar is not intended to follow all the requirements of native packages and cannot be reused for distribution of official repositories, i.e., Zero Sugar is NOT a meta-packaging tool.

There are only three major ideas behind native distribution support:

  • make packages, built on OBS, reusable for the 0install deployment model;
  • as a side effect, Zero packages could be installed on GNU/Linux distributions that OBS supports, also, Zero packages might be reused for OBS-based Sugar distributions;
  • Zero Sugar does not support most of the 'devil-in-details' packaging features that make distro people's life so funny.

Each OBS package is generated by the 0sugar tool, and might be built on a bunch of rpm/deb-based distributions within OBS. It is possible to follow regular OBS procedures for Zero packages, e.g., creating links and branching them.
