apt-get dist-upgrade and powerfailure

[Matt Grant]

I was doing an dist-upgrade from 2.1 to 2.2 and my power went out. Data is 
backed up but I had to rush out of the house to work. I didn't get to boot 
the system. When I do what should I expect. Will I need to format or will It 
begin where it left off(Just Hopeing). Any tips or suggestions would be 
appreciated.
