Some of the tests that we run in this stage (where we have all the RPMs,
but not necessarily an installable distro) is:

1.  All the RPMs seemed to install properly on a running system.

2.  That the dynamic libraries linked by all the libraries/binaries are
the same as upstream.

3.  That the file list of every RPM we produced is identical to the file
list of every RPM from upstream.

4.  That the trees contain the correct versions of all files (the same
ones on the .0 isos from upstream).  We want to make sure the updates go
into the updates directory.

5.  That the comps.xml (compilation) file has the correct groups in it.
 Upstream has several different versions of their codebase that they
sell for different amounts ... ie:
  a.  Server
  b.  Workstation
  c.  Desktop

CentOS has no need for the segregation, our product is free and contains
all the packages (and yum install groups, etc.) from all of those combined.

We also remove several packages (all the RHN items, for example, since
CentOS is not allowed to update from RHN, etc.)

This requires us to take the applicable portions of several comps files
and build a combined comps file that allows you to install Servers,
Desktops, Workstations, etc.

6.  In the case of 6.0 specifically, there is an "optional" channel that
contains many of the -devel (development) files needed to build things.
 We also have no need for that, but we need to get the items in that
channel integrated into our distribution and comps files.

Once we get all of these things done and tested, then we can generate a
set of real ISOs and test the install groups, etc.
