Also, one possible way to potentially mitigate this danger with yet 
another device mapper trick would be to-

After installation, create a snapshot of the system disk(s), then boot 
them headlessly under qemu in some way that you could tickle them into 
proving that the bootloader worked (perhaps an init script that detects 
this type of test qemu run, and provides some output than can be caught).
