dlehman's patch

Sometime ago I discussed with David Lehman how to create several partitions without transaction management in Anaconda.

I want is this to work:

def createPartition(storage):
    part1 = storage.newPartition(disks=[disk], size=100, grow=False)
    action1 = pyanaconda.storage.deviceaction.ActionCreateDevice(part1)
    storage.devicetree.registerAction(action1)
    pyanaconda.storage.partitioning.doPartitioning(storage=storage)
    disk.format.resetPartedDisk()
    action1.execute()

If I run this function once, it works as expected and creates one partition. If I run it twice, the second call raises:

  File "/usr/lib64/python2.7/site-packages/pyanaconda/storage/deviceaction.py", line 241, in execute
    self.device.create()
  File "/usr/lib64/python2.7/site-packages/pyanaconda/storage/devices.py", line 787, in create
    raise DeviceCreateError(str(e), self.name)
DeviceCreateError: ("Can't have overlapping partitions.", 'sdc3')

We agreed with David on some preliminary patch(attached), which solves the issue with disk.format.resetPartedDisk(). But the patch did not went to Anaconda upstream.
