This has been an exciting week of code analysis and debugging. As I mentioned previously cobbler doesn’t currently have support for Fedora 27. It it turns out adding a new Operating System signature is super easy. For my specific situation I forked the cobbler git repo and copied the Fedora 26 signature line and changed the 6 to a 7. Once I updated the signature file and restarted cobblerd everything imported without issue:
$ cobbler import --name=fedora27 --arch=x86_64 --path=/mnt
