[Bug 856826] Re: 'guided resize' partioning leaves Mac unbootable

[Colin Watson]

So, I think I've managed to fix this.  Unfortunately, I don't actually
have hardware to hand so that I can test it directly.  I've written a
test script which exercises as many cases as I can think of, and they
all pass now, but the real test will be trying this on actual hardware.
As such, please try tomorrow's daily build, and if it still goes wrong
then please do let me know and reopen this bug.

** No longer affects: grub2 (Ubuntu)

** No longer affects: grub2 (Ubuntu Precise)

** Package changed: partman-base (Ubuntu Precise) => parted (Ubuntu
Precise)

Bug description:
  After installing with ubuntu-oneiric-alternate-amd64+mac.iso (ISO from
  2011-09-21) this MacBookPro6,2 is not bootable. I used the 'guided
  resize' partitioning option to split an existing ext4 partition to
  make space. The original system was working fine and the resulting
  partition table, after the install, looks reasonable (two ext4
  partitions, two swap parititons, and a bios_grub partition).

  This would appear to be a regression. If I remember rightly, this
  worked correctly in Oneiric once before.
