Inspired by recent fedora-devel list discussion, here's a patch to save
some space from images by excluding obsoleted packages. Arguably those
packages should just die and not hang around in the repos, but these
undead packages seem fairly persistent...
This is what I see with F18 install DVD:
Before patch:
-rw-r--r--. 1 root root 4687134720 Nov 12 21:10 Fedora-18-x86_64-DVD.iso
With the patch:
-rw-r--r--. 1 root root 4550819840 Nov 12 21:01 Fedora-18-x86_64-DVD.iso
This is what makes up the difference:

Subject: [PATCH] Exclude obsoleted packages from images
Avoid dragging undead packages which would just be replaced by something
else in the next 'yum update' into space-constrained images.
