One thing left to mention, just for the files:

"And so on": The partition IDs have to be adapted also:

When the SD card is mounted on a Linux workstation, then the two
raspberry partitions will show up as (e.g.) /dev/sdb1 and /dev/sdb2 or
similar -- just verify. Then get their partition names with blkid /dev/
sdb{1,2} and update boot/cmdlist.txt and rootfs/etc/fstab on the SD card.

Otherwise your cigarette box won't boot.

Markus
