Comment 3 for bug 850892

The only thing that comes into my mind right now is download the new iso, mount it, then rsync it to the location where it lives whithing cobbler, and then do cobbler sync.

Cobbler sync should re-create the hardlinks, as it puts the kernel and initrd in a different location, which are used by the PXE file.

Other thing that comes into my mind is to:

1. Download new ISO
2. Import it with oneiric-<date>-<arch>
3. Change the child profile (-ensemble) to point to the parent profile above (oneiric-<date>-<arch>)
4. Remove old profile

This way, we would point the -ensemble profile to the newly imported, and then, once the old one is removed, then the systems wont be deleted as the -ensemble profile will be pointing to the newer profile at the time of deletion.
