RPM roadmapping

[Arthur Pemberton]

* Rollback and Repair feature (in the idea of Windows Restore,
assuming that works)

* Easier/clear database repair

* installation type status (installed as a dependency, or not) - would
make streamlining an installation easier

* (this one may exist in some form, i don't know) some way to tag a
package as a library, headers, server, client, standalone, so I could
essentially yum list servers at some point
