The new element controls the behavior of the repart/resize code
in the oem-repart dracut module. By default the repart/resize
happens on every reboot and therefore also allows for disk
geometry changes during the livetime of the machine. If the
element is set to false the repart/resize operation happens
only once and then never again. To check for this condition
a new profile environment variable kiwi_rootpartuuid which
holds the PARTUUID of the root partition has been added to
the disk builder.
