When specifying an offset for the partition, can it be used safely without specifying its limits (size) ? What if I have another partition at the end of the one I need - isn't there a chance it will be overwritten?
What I meant by /dev/loop0p1 (look at a file in fdisk), is whether there's a way to access the partition directly, through the kernel facilities, instead of figuring out the byte offset of the partition manually. - Itay.
