Description of problem: The kernel should import certs stored in the MokListRT UEFI variable provided by shim. This will be the basis for making 3rd party signed modules and/or self-signed kernels work in a Secure Boot environment. This is already implemented in f18 with this build: http://koji.fedoraproject.org/koji/buildinfo?buildID=372260 Rawhide also has the code in git already and should show up in a build within a day or two.
Proposing as F18 NTH. Without this support, third party signed modules are still doable, but are much less user friendly. Users would need to go through the firmware interface directly to import a cert into the UEFI db variable instead of using the 'mokutil' utility from userspace provided by the shim package.
