[Yum] Obsoletes within the same transaction set

[Jeff Pitman]

Hi:

Is obsoletes processing being run with a groupinstall?  I have the 
following for a mock chroot: /usr/sbin/mock-helper yum 
--installroot /var/lib/mock/centos-4-i386/root 
-c /var/lib/mock/centos-4-i386/root/builddir/mock.conf groupinstall 
build --obsoletes   

However, if I have--in the same transaction--python = 2.4.1 and python24 
trying to obsolete it, rpm does not process this.  So, does that mean 
groupinstall only executes with "-i" and not "-U"?
