Doing away with 'groups' repo in mock

[Jesse Keating]

Currently mock configs make use of a 'groups' repo to provide 
a 'buildsys-build' meta-package.  This meta-package has a set of Requires: 
that are used to create the 'minimal buildroot' mock uses to start builds.  
This repo also provides a 'buildsys-macros' package.  Historically this 
package would define things like the %dist tag and post-build actions.

Today, in rawhide, fedora-release provides the %dist like macro definitions.  
The post-build definition can be moved to redhat-rpm-config as well.  This 
would obviate the need for buildsys-macros.  That would just leave the 
meta-package to populate the buildroot.

Since mock supports installing a group rather than a (meta)package, I propose 
we define the buildsys-build group in the comps group directly.  This would 
obviate the need for a single point of failure within mock building, 
the 'groups' repo.

Here is the change I would make to comps:

The comps change can be made at any time, however changes to mock need to be 
coordinated with the maintainer for redhat-rpm-config.  I'd also like to 
move /usr/lib/rpm/check-buildroot out of rpmdevtools and into one of the 
packages already being pulled into the buildroot (redhat-rpm-config perhaps, 
since it will be referencing it?), and thus we'll need to coordinate with the 
rpmdevtools maintainer.

We wouldn't be doing away with mock's ability to just use a meta-package to 
populate the root, so those that want to alter what goes into the buildroot 
can (just like before) build your own buildsys-build package and host it for 
your mock, or define your own comps grouping, etc...  

Comments?
