[arch-projects] [mkinitcpio][PATCH 0/9] Resend of pre-kill gen-init-cpio

At Thomas's request, this is a resend of the patchwork that precedes the patch series to kill off gen_init_cpio. I've made some minor tweaks, the only notable one being that I've dropped support for PARTUUID= out of patch 7. It's not right to use PARTUUID as a synonym for UUID because PARTUUID actually refers to the GPT partition UUID, and not the filesystem UUID. blkid can't (currently) resolve this, so we'll stash this for now and await proper support in libblkid. d
