Comment 12 for bug 1564977

Just to clarify on what would MAAS need.

13:42 < rharper> if you know it's 4k, you need to ensure that the partition is at least 512MB, no smaller; it can only be uefi
13:42 < rharper> curtin doesn't need to know the block-size, we;ll figure it out
13:43 < rharper> the EFI partition, and GPT only; that should be sufficient
