[revisor-users] Empty repodata/comps.xml file ?

Hi all, I am using Revisor (revisor-2.0.5-15.fc8) to respin a CentOS ISO with only the default base, core groups and some custom packages in a group I specified. I created a comps.xml file that is based off the comps-c5.xml and a very simple kickstart file based off centos-5-ks.cfg. The comps.xml has pretty much the same base and core groups, except all the "xml:lang" lines have been removed (English only installer) and a new group added (with my packages) and a new category that includes my group+base+core. The kickstart file has only my custom group specified in the "%packages" section. I do get a valid ISO file with about 450 rpms in it, including my custom packages. However, when installed, this ISO results in an installation that is skeletal - kernel, shell and little else (not even vim). After digging around, I found that the ISO being built has an empty ISO:/repodata/comps.xml file. I guess that the skeletal installation is the result of an empty comps.xml file i.e. <comps />. As far as I can tell, this /repodata/comps.xml originates from /var/tmp/revisor-pungi/VERSION/MODEL/comps.xml and this file is created sometime after the packages are downloaded but before pkgdir is created. I'd appreciate any suggestions on: A) Why the ISO installation is skeletal - is it really because of an empty repodata/comps.xml file? B) What do I need to tweak in order to fix this issue?
