Triggered by the firmware="vboot" setup an EFI setup plus a
raw partition without filesystem is created as first partition.
The size of the partition can be controlled by the vbootsize
attribute. The vboot feature is used by the arm architecture
to provide a space in the partition table for custom code as
required by e.g the chromebook. The final customization of the
vboot space is board specific and can't be implemented in a
generic way in kiwi. For finalizing the vboot space the script
hooks editbootconfig and editbootinstall can be used

file from information provided with the optional pxedeploy
section. However this is not fatal to the build because the file
could be created manually too. Thus a warning message is shown
which will go away when the pxe client config file creation
has been ported
