Glob expressions are normal strings of characters which contain one or more of the wildcard characters <command>*</command> (which expands to match any character multiple times) and <command>?</command> (which expands to match any one character). Be careful to escape both of these glob characters when passing them as arguments to a <command>yum</command> command. If you do not, the bash shell will interpret the glob expressions as <emphasis>pathname expansions</emphasis>, and potentially pass all files in the current directory that match the globs to <command>yum</command>, which is not what you want.

<para>The <application>presto</application> plugin adds support to <application>Yum</application> for downloading <firstterm>delta RPM</firstterm> packages, during updates, from repositories which have <application>presto</application> metadata enabled. Delta RPMs contain only the differences between the version of the the package installed on the client requesting the RPM package and the updated version in the repository. Downloading a delta RPM is much quicker than downloading the entire updated package, and can speed up updates considerably. Once the delta RPMs are downloaded, they must be rebuilt (the difference applied to the currently-installed package to create the full updated package) on the installing machine, which takes CPU time. Using delta RPMs is therefore a tradeoff between time-to-download, which depends on the network connection, and time-to-rebuild, which is CPU-bound. Using the <application>presto</application> plugin is recommended for fast machine
s and systems with slower network connections, while slower machines on very fast connections <emphasis>may</emphasis> benefit more from downloading normal RPM packages, i.e. by disabling <application>presto</application>. The <application>presto</application> plugin is enabled by default.</para>

<para>The <application>protect-packages</application> plugin prevents the <filename>yum</filename> package and all packages it depends on from being purposefully or accidentally removed. This simple scheme prevents many of the most important packages necessary for your system to run from being removed. In addition, you can list more packages, one per line, in the <filename>/etc/sysconfig/protected-packages</filename> file<footnote
id="footnote-Alternative_Locations_for_protect-packages_Lists"><para>You can also place files with the extension <filename>.list</filename> in the <filename>/etc/sysconfig/protected-packages.d/</filename> directory (which you should create if it does not exist), and list packages—one per line—in these files. <application>protect-packages</application> will protect these too.</para>
