So the gain is the ability to abort the rescue shell if the root device shows 
up after the timeout?  Couldn't this be done instead with a small tweak the the 
existing scripts so they run the rescue shell in parallel with continuing 
wait-for-root without a timeout, and if it returns, kill the shell?
