Ben's email: """ The root of the problem is that the root device is mapped to /dev/sda. The swap device is mapped to /dev/sda3. I think that this probably confusing UDEV, since normally, /dev/sda is used at the device identifier and /dev/sdaX[1-9] is used as the device partition mappings. EC2 maps both /dev/sda and /dev/sda3 as block devices. From the kernels perspective, it doesn't care. I believe that if you change the block mapping for the root device from /dev/sda to /dev/sda1, this should fix the problem for you. I haven't had a chance to test the theory, but it would get around that suspect rule and not require any other changes than a re-registration of the AMI. """

Does it help with sda1 vs. sda and LABEL=root vs LABEL=/ ?
/dev/sda1 was the trick. Thanks Harald!
