7.3. Yum Changes

The installonlyn plugin functionality has been folded into the core yum package. The installonlypkgs and installonly_limit options are used by default to limit the system to retain only two kernel packages. You can adjust the package set or the number of packages, or disable the option entirely to match your preferences. More details are available in the man page for yum.conf.
The yum command now retries when it detects a lock. This function is useful if a daemon is checking for updates, or if you are running yum and one of its graphical frontends simultaneously.
The yum command now understands a cost parameter in its configuration file, which is the relative cost of accessing a software repository. It is useful for weighing one software repository's packages as greater or less than any other. The cost parameter defaults to 1000, with lower costs given priority.
In Fedora 9 Rawhide, the /etc/yum.repos.d/fedora-development.repo file has been changed to /etc/yum.repos.d/fedora-rawhide.repo. References to development in fedora-rawhide.repo have been changed to rawhide. Due to the way that RPM deals with configuration files, the existing /etc/yum.repos.d/fedora-development.repo file is saved as /etc/yum.repos.d/fedora-development.repo.rpmsave if it was previous modified. Users of the development repository may need to update scripts custom configuration files to use the new name.
