That's the normal way, yes. exec does the rest (including running
startup).

Well, using sparse files can work as well: create the image with

dd if=/dev/zero of=file.img bs=1M count=1 seek=1000

and pass -S to tar so that on decompression it gets sparse too.

The advantage is that standard tools (fdisk, etc.) will work on it.
