I helped to create a simple script which could assist in the automation and creation of ARM-based images after standardized tools like kickstart, lorax, and livemedia-creator have been used. The problem is that some ARM devices (like OMAP) require there to be a FAT partition and filesystem listed first which contains proper binaries to assist with the initial booting process. Since x86 machines don’t have this requirement, their creation tools don’t include an option to help set this up. The python script listed below helps to take an outputted image and just modify it slightly to meet these requirements for us automatically. Here is an example of the output along with its source code.

# fdisk -l F18-panda-20121218.img
