[Bug 1212492] Re: cc_growpart broken if parted resizefs found

[Phillip Susi]

You have to not use --script and parse the output for the warning and
answer yes.  I have been mulling over a --force-things system to allow a
script to specify that it expects a specific error and how it should be
handled but it isn't easy the way libparted is structured.

Bug description:
  As reported in bug 1212444, the partition growing is broken if growpart is found to be usable.
  There are 2 things that are broken,
   a.) we invoke parted wrong (passing device after 'resizepart' rather than before)
   b.) parted seems somewhat broken, and I dont know how to force it to do what we want.  See:

  $ sudo parted /dev/vda resizepart  --script 1 </dev/null; echo $?
  Warning: Partition /dev/vda1 is being used. Are you sure you want to continue?

  Um... yes, parted, i want you to do what I told you to do.
