Actually, sometimes I would like to switch to the next generation ("-roll-
forward", in a sense): I install something, go back with "--roll-back",
and might like to go just one forward again.

So how about the following:
--switch-generation=1
goes to generation 1;
--switch-generation=-1
goes 1 generation back;
--switch-generation=+1
goes one generation forward.
