Comment 0 for bug 1041186

When landing a pipeline of branches, with prerequisites, Tarmac does land in order that they're approved, so it may attempt to land a later branch first, resulting in:

  The prerequisite lp... has not yet been merged into lp:maas.

For example, see https://code.launchpad.net/~allenap/maas/pxe-intel-arch-config-2/+merge/121097.

It would be great if Tarmac were able to sort by the approval time and work through the branches in order.
