Red Hat Network and the Red Hat errata list both give you the packages and tools you need to update your system with the latest security patches, bug fixes, and package enhancements. Red Hat Network does much of the work automatically, as opposed to the manual procedure of updating from the errata list. This chapter covers the basics for both.
Please note that this chapter is not intended to serve as a complete reference guide for Red Hat Network or errata.
