Anaconda dumped with rpm:error match tag missing after doing a genhdlist 
on an modified and unmodified copy of cdrom for network installs

How reproducible:
Always

Steps to Reproduce:
1. cp -a /mnt/cdrom/* ~/cd1
2. cp -a /mnt/cdrom/* ~/cd2   - the second cd
3. add rpm to /mnt/cdrom/RedHat/RPMS
4. /usr/lib/anaconda/genhdlist --withnumbers --hdlist 
~/cd1/RedHat/RPMS/base/hdinst ~/cd1 ~/cd2
5. do a nfs install to this machine
6. error is generated	

Actual Results:  you really want the floppy dump?
