It appears that this was added to prevent ppc64 reboot loops. https://github.com/cobbler/cobbler/commit/bc76631ea158c76b1cdc8d3af28c9dc... I know that we had the potential for reboot loops even on regular x86 hardware, but we dealt with it without code change. Our systems boot harddrive then netboot. So on initial install they netboot, once there is an OS they regular boot. If you need to re-install you either use koan or function key to select network boot at boot time.

That being said, our systems also turn static post-install, so this change would not affect us. However, if we ran off DHCP period we would have the same issue you are experiencing with this. Maybe the better check would be: if not interface["netboot_enabled"] and interface['static']: continue ?
