Description of problem:
1) Testing Installation with Fedora non-media install (Rawhide). i.e., kernel + initrd with options set for ip boot.
2) Using gummiboot for booting instead of grub (documentation used grub)
3) Appears that most programs calling efibootmgr fail, but when efibootmgr is called manually to remove a boot entry, it works. Refind install from arch had pretty much the same problem. 
4) May be affected by setting BIOS to non-writeable. Uses Sandy Bridge CPU and does not support Secure Boot.
5) I think that grub installed fine, up to trying to add itself to the EFI boot list.
