Tried to install the f11 beta tree from 2009-03-22 using a kickstart containing e.g.:

  part /boot --fstype ext3 --size=200 --onpart=sda1

and got this traceback:

  File "/usr/bin/anaconda", line 993, in <module>
    kickstart.processKickstartFile(anaconda, opts.ksfile)

    ksparser.readKickstart(file)

    obj = self.commands[cmd].parse(args[1:])
  File "/usr/lib/anaconda/kickstart.py", line 678, in parse
    devicetree.registerAction(ActionCreateFormat(device, kwargs["format"]))
  NameError: global name 'ActionCreateFormat' is not defined

Looks like kickstart.py is missing:

  from storage.deviceaction import *
