Config drive creation fails in UEFI boot mode for whole disk image

[Shivanand Tendulker]

Config drive creation fails when whole disk image is being deployed in UEFI boot mode using IPA ramdisk.

In UEFI boot mode when parted tries to create additional disk for Config drive, it gives following warning:

Warning: Not all of the space available to /dev/sdb appears to be used,
you can fix the GPT to use all of the space (an extra 2097152 blocks) or
continue with the current setting?

To create a new partition this warning needs to be fixed. Upon fxing this warning, creation of new partition goes through.

Further Analysis:
----------------------------
The parted command cannot fix this warning in scripted mode. It can be fixed only using interactive mode. There was a defect being opened on this behavior log time ago and was not fixed then.

The issue has been reproduced with IPA based on Fedora 22 which has parted version of 3.2

This means this warning needs to be fixed using 'expect' (Expect is a tcl extension for automating interactive applications)

    Fixes config drive creation failure in UEFI boot mode

    This fix enables creation of config drive for UEFI only whole disk
    images.
    It will not work with the hybrid images that support booting in BIOS
    and UEFI boot mode.
