Description of problem:
For modularity and other reasons, I have kickstarts using the %include directive in the %packages section and have done so dating back to Fedora 10.  In Fedora 17, this no longer works.

Version-Release number of selected component (if applicable):
livecd-tools-17.11-1.fc17.x86_64

How reproducible:
always

Steps to Reproduce:
1. Customize a trivial kickstart, say /tmp/test.ks, so as to have %packages mention something like "%include /tmp/test-packages.ks"
2. Create /tmp/test-packages.ks with a list of a few package names, just like they might appear in the %packages section.
3. Try to create ISO image using /tmp/test.ks.

Actual results:
I receive an error message like:
Error creating Live CD : Failed to find package '%include /tmp/test-packages.ks' : No package(s) available to install


Expected results:
Should create ISO image as if packages named in /tmp/test-packages.ks were included directly within /tmp/test.ks.


Additional info:
The last spin I'd made with livecd-tools was on Fedora 16, about a few weeks ago, and that worked fine.  I believe I used livecd-tools-16.15-1.fc16.x86_64 since I see that was installed May 23, 2012.
