Maybe for a boot-image?  You boot the system on a tiny boot disk with 
the drivers you need to mount the real root then mount the real root 
over yourself?  I'm not quite sure why that would be better than 
pivotroot though.

I'd back a --really flag or a '-o clobberroot' in mount(8).  There are 
plenty of unix tools that let you clobber your system without any 
warning so you might get some purists against it.
