© Novell, Inc. XBS Package Management Package management provides a way to easily install, upgrade, remove, or otherwise manage software on a system Most popular packaging systems on Linux are RPM and Deb PKG

© Novell, Inc. XBS Package Anatomy Metadata is contained in a file used by packaging tools (e.g., spec file) Metadata is often similar across packaging systems Actual file format varies Some tools want to help you build the software as well Delivered software Package Metadata file lists md5sums dependencies description etc

© Novell, Inc. XBS Core XBS Functions Source and patch management: Retrieve pristine sources and out-of-band patches from CVS or the BB repo Package creation: Build and package a software module from a “ conf ” file Package verification: Check for common packaging mistakes bb_build engine: Performs operations on groups of modules, with dependency ordering

© Novell, Inc. XBS Basic XBS Operation 1. bb_unpack gets the sources of the module (from the repo, or from cvs), as well as all the patches. It unpacks the sources and applies the patches 2. bb_do creates the package system-specific files (e.g., "spec" file for rpm), builds, and makes the packages 3. bb_lint runs several automated checks on the packages to verify correctness and warn of possible mistakes
