The kickstart entry, as defined, should define a partition of max size
'cos you only have one --grow value
  part / --fstype=ext4 --asprimary --grow --size=1

In my tests the partition always fills the disk allocated to it, so there's
no need to resize after install.

  # fdisk -l

  Disk /dev/vda: 4294 MB, 4294967296 bytes
  16 heads, 63 sectors/track, 8322 cylinders
  Units = cylinders of 1008 * 512 = 516096 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disk identifier: 0x000666f1

     Device Boot      Start         End      Blocks   Id  System
  /dev/vda1   *           3         206      102400   83  Linux
  Partition 1 does not end on cylinder boundary.
  /dev/vda2             206        1246      524288   82  Linux swap / Solaris
  Partition 2 does not end on cylinder boundary.
  /dev/vda3            1246        8323     3566592   83  Linux
  Partition 3 does not end on cylinder boundary.

Under what circumstances is a resize needed?
