pungi on i386 to build x86_64?

[Phil Meyer]

The are some comments in the generic pungi.conf that indicate that a 
i386 based Fedora can only roll releases for i386.

For this question please assume that no sources are being recompiled or 
gathered for the release.

Is this still correct?

What happens, is that the .discinfo fails to be created.

Here is the python error:

Traceback (most recent call last):
  File "/usr/bin/pungi", line 187, in <module>
    main()
  File "/usr/bin/pungi", line 125, in main
    mypungi.doCreateSplitrepo()
  File "/usr/lib/python2.5/site-packages/pypungi/pungi.py", line 278, in 
doCreateSplitrepo
    discinfo = open(os.path.join(self.topdir, '.discinfo'), 'r').readlines()
IOError: [Errno 2] No such file or directory: 
'/srv/pungi/RHEL5_x86_64/5/Custom/x86_64/os/.discinfo'

I have seen previous questions related to rolling RHE releases from F7, 
but is it that or the arch issue?

Thanks!
