Hi,

bug 264685 (Get rid of package locks in package manager) asks for
reasoning of and better concepts for locking packages in the package
manager.

This mail should be a kickoff to define a common understanding
and concept for package locks.

Package locks try to provide a solution for the following
use-cases

1. Distribution upgrade with 3rd party packages

   Desktop user Joe has purchased a full featured version of
   the FooBar application from vendor ACME for openSUSE 10.2
   The new openSUSE 10.3 distribution contains a free version
   of FooBar, based on open source, built in autobuild with
   vendor 'openSUSE', with limited functionality.

   Upgrade of the distribution replaces the full featured
   version with the limited one.

2. Maintenance upgrade of 3rd party packages

   Multimedia junkie Susan likes to listen to mp3 encoded
   music files and regularly watches DVD movies on her laptop.
   Because of license issues, she installed mplayer from a
   3rd party repository, including a full set of patented codec
   implementations.
   The openSUSE project provides a maintenance update for
   mplayer, fixing a critical security bug. This update replaces
   the installed mplayer, resulting in a version with limited
   functionality.


The current solution to the above scenarious is to group packages
based on their vendor attribute. Packages from unknown vendors
are auto-protected in order to prevent unwanted replacements.

This is a very effective but also very limited solution.

Proposals anyone ?
