Bug Description

On EFI systems, the Ubuntu GNOME Remix image don't boot and we get this error message:

error: file `/casper/vmlinux.efi.signed` not found.
error: you need to load the kernel first.

Also, looks like we miss some genisoimage parameters that will cause boot to fail at all on some EFI systems.

This is supposed to fix the first issue but after make a clean image:

http://bazaar.launchpad.net/~ubuntu-gnome-dev/+junk/iso-build-script/revision/28

But we miss the vmlinuz.efi.signed at casper folder, this is fixed on:

It is the approach used by Ubuntu Release image, on daily images EFI secure boot stuff is not included, also for Kubuntu (release image) this secure boot stuff is also not included.

Also, we need to apply this patch even if we are not going to have secure boot stuff:

Just checked now and the other flavors of Ubuntu (Kubuntu, Xubunu and Lubuntu) don't include secure boot stuff.

Are we going to follow Ubuntu or other flavors?

cjwatson just sugest us to make sure have installed grub-efi-amd64-signed and shim-signed as well.

I think we should keep secureboot, as per cjwatsons comments...

Looks like we should be right, just need to build iwth -updates enable to ensure we get the updated ubiquity >= 2.12.15, which is an absolute requirement for secureboot installations.

Keeping secure boot.

FWIW edubuntu shipped with secureboot support. It was up to the various flavours to seed the right kernel and grub packages to get secureboot support. However it would cause a ~15MB extra disk usage which wasn't possible for some flavours.

Ok, we already have comment #6 since we start with the Ubuntu image as a wrapper, create our own squashfs, tweak a few things in the wrapper (isolinux theme, identifying as Ubuntu GNOME, etc.), and then just build the ISO from all of that. Those two packages are already included in pool/ .

I've merged everaldo's branch and am rebuilding the image now.

Ubuntu GNOME Remix 12.10.1 is now available for amd64 with this fixed. Generally speaking, EFI is only supported on amd64.
