#### EZ Templates Repository

One of the basic concepts in the EZ template technology is the concept of 'repository' where RPM packages for the given EZ template are stored. A repository is a prepared directory or web site containing software packages and index files for Linux operating systems and/or any of their applications. An example of such a repository is the repository located at the http://mirrors.usc.edu/pub/linux/distributions/fedora/ web site and storing RPM packages for the Fedora Core releases. Using repositories gives you the following advantages:

- RPM packages included in the given EZ template do not contain versions, but only names (e.g. bash, crontabs). So, you always update any RPM package included in the EZ template to its latest version available in the repository.
- As a result of the fact that a list of RPM packages does not provide their versions, EZ templates do not have versions either (e.g. redhat-as4-x86). Thus, you install any EZ template on the Hardware Node only once and, after that, use the installed template to update the RPM packages inside any Container where it is applied.
