chain load with EFI and file:/ URL

Running dhcp beforehand actually helped, it now boots into file:/etc/redhat/grubx64.efi but does not load grub.cfg. It seems to me that file:/ URIs are intended for loading things like iPXE scripts but are not completely implemented for chain loading.

It looks like the the environment is not set up correctly. If I try to load file:/etc/redhat/shim.efi, which is supposed to load grubx64.efi in the same directory, it fails:

Code:

dppath: shim.efi
path:    shim.efi
Failed to open grubx64.efi - Not Found
...

So again, is this supposed to actually work? Has anybody ever tried to chain load an EFI image from a local disk and succeeded?
