We tried that.  It suffers for 'development/deploy' in that you want the
binaries compiled with the exact same options and configuration.  It
makes a lot of sense to use subpackages for this.  The rpms are created
by extracting files from the same build tree.  Also, the tree only
builds once as opposed to twice.

'subpackages' don't work as well for multi-arch, etc. where the binaries
might be different between rpms.  I guess that is a key difference
between what 'rootn', etc are trying to accomplish.

Thanks again,
Bill Pringlemeir.
