curl http://d-i.debian.org/daily-images/amd64/20110531-00:15/hd-media/initrd.gz | gunzip -c | cpio -i -t | grep _id lacks edd_id, while curl http://d-i.debian.org/daily-images/amd64/20110501-00:14/hd-media/initrd.gz | gunzip -c | cpio -i -t | grep _id includes it. Just in case this helps track down the change. Thanks, -neil
