uck-remaster-finalize-alternate does not work with trusty beta1

[Red_Phoenix]

GOOD: The ubuntu-archive-keyring file within the rebuilt ubuntu-keyring package DOES contain the new signing keys

GOOD: The ubuntu-archive-keyring udeb and deb are on the final CD

GOOD: All packages and Release files seem to be correct, and signed appropriately on the CD

BAD: During installation of the resulting CD, "No kernel was found" error appears due to:
* The file /usr/share/keyring/ubuntu-archive-keyring is a baseline version, with only the ubuntu CD signing keys on it - it does NOT contain the keys found in the rebuilt ubuntu-keyring-<version>.udeb OR ubuntu-keyring-<version>.deb on the CD:
# chroot /target/bin/bash
# gpg --keyring /usr/share/keyring/ubuntu-archive-keyring --list-keys
# dpkg -i /media/cdrom/pool/pool/main/u/ubuntu-keyring/ubuntu-keyring_2012.05.19_all.deb
# gpg --keyring /usr/share/keyring/ubuntu-archive-keyring --list-keys
(Note that keys are different).

* apt-cdrom fails due to the fact that /dists/trusty/Release.gpg cannot be validated

Possible fixes:
* ubuntu-keyring needs to be installed before the apt-cdrom call. No simple way that I can see, in preseed, to do this. early_command is too early; late_command is too late.
* Whatever package is installing the baseline ubuntu-archive-keyring (possibly as a copy of /etc/apt/trusted.gpg ?) may need to be modified in addition to ubuntu-keyring
