This leads to unexpected change of first partition's size, and is not matched by similar adjustment at the time the partition image is generated. Thus it is possible that the first partition may partially overwrite contents of the following partition, as the partition image is larger than the allocated space. This is also problematic on certain platforms such as OMAP, where the first partition is required for have an even number of sectors (typically already expressed by --size in kickstart file). Subtracting an odd number of sectors lost for overhead, leads to an odd number of sectors assigned for partition, preventing the board, such as beaglebone, from booting correctly.
