[Bug 972122] Re: Ubiquity pops out a warning message from partman-partitioning on UEFI BIOS when there is a EFI system partition existed.

[Colin Watson]

I can see what you're trying to do with this patch, but I think it's a
workaround for the real problem, which is that the EFI partition isn't
being detected.  I'd prefer to fix that instead.  Doing so would
probably also fix bug 900245.

In the case of GPT partition tables, we can reliably detect existing EFI
System Partitions using something like this:

  [ "$(blkid -o value -s PART_ENTRY_TYPE "$path")" = c12a7328-f81f-11d2
-ba4b-00a0c93ec93b ]

** Package changed: partman-partitioning (Ubuntu) => partman-efi
(Ubuntu)

** Changed in: partman-efi (Ubuntu)
       Status: Confirmed => Triaged
