[DC LoCo] Upgrade from 10.10 -> 11.04 took two days to recover from

[Ken Stailey]

How would a fresh rebuild be any better?  I'd still be stuck with a system that won't boot from my disk configuration due to a driver bug.

As-is it turned out having my complete system installed but unbootable enabled me to me be recover by using it as a chroot environment.
