Description of problem: Composing an Install DVD for Fedora 16 x86_64 using pungi+lorax(treebuilder) gave cascading errors after failing to download a package destined for the initramfs.  Continuing when possible is good intent, but this case revealed further error(s) that gave poor overall results.


Version-Release number of selected component (if applicable):
lorax-17.0    7f8a5e48b30a02afd6f9a71274a09ba73f892d60  (HEAD of treebuilder branch as of 2011-10-24 15:49:39)

How reproducible: haven't tried


Steps to Reproduce:
1./usr/bin/pungi -c fedora-install-fedora.ks \
	--destdir=$DESTDIR --name Fedora --ver $VERSION --nosource
designating the Fedora 16 repos fedora, fedora-updates, fedora-updates-testing.
