Currently we add padding between the bootconfig text and footer to ensure that the footer is aligned within the initramfs image. However, because only the bootconfig data is held in memory, not the full initramfs image, the footer may not be naturally aligned in memory. This can result in an alignment fault (SIGBUS) when writing the footer on some architectures, such as sparc. Build the footer in a struct on the stack before adding it to the buffer.
