Description of problem: shim is not currently signed by the UEFI signing service. That means new machines won't boot.
Discussed at 2012-11-01 blocker review meeting: http://meetbot.fedoraproject.org/fedora-qa/2012-11-01/f18beta-blocker-review-6.5.2012-11-01-17.49.log.txt . Agreed this is rejected as a blocker as far as the blocker process goes: it is a conditional violation of "The installer must boot (if appropriate) and run on all primary architectures, with all system firmware types that are common on those architectures, from default live image, DVD, and boot.iso install media when written to an optical disc and when written to a USB stick with at least one of the officially supported methods" in the case of an SB machine with SB enabled, but we don't believe those are yet prevalent enough to block a Beta release for. However, it's accepted as NTH, as it would be great to have the Beta SB testable OOTB. Note that SB support is also a feature for F18, so FESCo could delay the release for this under the feature process. The feature process is separate from the blocker process by policy.
