I do use separate pictures in each desktop for ease of identification. It would probably be helpful to use partitian names.

I cannot think of any fingerprints left by the loader other than perhaps "boot-once" from grub. Perhaps you can add a command in through a section of grub whereby you can talk to a file so you could query it.
