[Cooker] gendistrib without SRPMS ?

[Frank Griffin]

In trying to upgrade 9.1 to Cooker from a local file mirror, I was 
running gendistrib and getting the message "unable to find a valid root 
directory which contains SRPMS".  I didn't realize that this was 
actually causing gendistrib to abort before updating the lists.

My local cooker mirror only contains the i586 directory, since I didn't 
think I needed source RPMs for anything.

Is there a way to run gendistrib without SRPMS ?  Is it correct that 
gendistrib run against --distrib /xxx/cooker/i586 should be requiring 
SRPMS ?
