disk 2: auto delete = false, size = 10, device name = "disk 2"

disk a: auto delete = false, size = 10, device name = "disk 2"
disk b: auto delete = false, size = 10, device name = "disk 1"
disk c: type = scratch
Then disk a will match disk 1, disk b won't match any disk, and c will match 3, making the
final order a, c, b, which is wrong. To get disk a to match disk 2, we have to go in order
of fields most specifically able to identify a disk to least.
