Paul's tip can work, but I found that there is another requirement: the 
r/w folder {i386} where subdir where .iso will be mounted {disc} must 
not have any other .rpm files any peer subdirs. Since my machine is laid 
/home/install/software/linux/fedora/core/6/i386/disc {dvd mounted here}
/home/install/software/linux/fedora/core/6/i386/yum {normal yum cache, 
keepcache=1, so that cache doesn't fill up /var partition}

If I then:
$ cd /home/install/software/linux/fedora/core/6/i386/
$ createrepo .
repodata is created at:
as expected, but the primary.gz includes all the rpms from the other yum 
folder {updates/extras and other repositories}.

If there is no other way to generate repodata in this situation, then I 
would like to suggest that an additional option needs to be added to

Any thoughts on whether such a command option should be implemented ?
