Claim 0:
1. A digital image processing device, comprising:
a memory, comprising:
a NOT-AND (NAND) flash memory having a boot volume, the boot volume including:
a primary boot partition configured to store a kernel component of a file,
a secondary boot partition configured to store a copy of the kernel component of the file, wherein the secondary boot partition is a back-up of the primary boot partition, and
a rootdisk partition configured to store a root filesystem of the file; and

a processor in operative association with the memory, the processor configured to operate via a device-mapper engine, wherein the processor is configured to:
split the file into the kernel component and the root filesystem;
generate a Squash File System (squashfs) image of a copy of the root filesystem;
write the squashfs image to the NAND flash memory; and
mount the squashfs image directly from the NAND flash.
