2nd Draft Ready for Review: Ch. 1: PackageKit

[Douglas Silas]

I have expanded the Yum chapter significantly since the 1st draft, 
and it should now be more-or-less complete. This is the last draft 
before I finalize the text for translation, so please send your 
comments/ suggestions! Especially if you think the Yum chapter 
should cover something important that it does not.

Note: Yum and its "ecosphere" (yum-utils, plugins, etc.) provide 
many more capabilities than can be described in the Deployment 
Guide. That said, I am very interested in Yum use cases and 
procedures that system administrators find indispensable. One 
example would be: documenting orphan and unneeded package removal 
with the package-cleanup command. Or merging config files with 
yum-plugin-merge-conf. Initial text for supplementary sections would 
be much appreciated.

Without further ado:

I have incorporated many suggestions from Rahul Sundaram and others 
into this draft. Thanks Rahul!

The (partial) list of changes:

* Yum plugins in general documented; specific ones (presto, 
fastestmirror, refresh-packagekit) now described
* chapter's 2nd paragraph is now a large admonition concerning GPG 
package verification and security, with links
* removing packages and groups now explained in detail, along with 
discussion of dependencies
* [main] and [repository] sections beefed up; new options explained
* improved command for creating Yum repos
* Additional Resources added (only one thus far)

Regards,
