Thanks for all the details .. currently trying to as well emulate the storage
device ... though I am stuck:

 "fdisk -lu backing file"
What is the "backing file"  ? You ment : "fake_storage_file" ?
"fdisk -lu fake_storage_file" gives me:
> Disk fake_storage_file: 64 MiB, 67108864 bytes, 131072 sectors
> Units: sectors of 1 * 512 = 512 bytes
> Sector size (logical/physical): 512 bytes / 512 bytes
> I/O size (minimum/optimal): 512 bytes / 512 bytes

... not sure where to get a starting offset from that output
