Comment 2 for bug 1597923

I'm marking verification-done, as curtin successfully creates whole disk fat partitions using the version in proposed. An example config file is attached.

On system used for curtin pack:

  # apt-cache policy curtin
     curtin:
       Installed: 0.1.0~bzr425-0ubuntu1~16.04.1
       Candidate: 0.1.0~bzr425-0ubuntu1~16.04.1

Note that the failure that this bug was reported for seems to only affect trusty and precise, and the mkfs.vfat tool on xenial seems to write whole disk partitions without the -I flag. However, it is still more correct to use the flag as the expected behavior of mkfs.vfat is to refuse to partition without the flag. This fix should also be SRU'ed to trusty
