I agree with your most common use case (which is incidentally my use
case), but I also think that the best way of serving that use case is
with an image file and a configuration file. As I see it, in that use
case, anything better than command-line options and scripts holding
them, is "extremely useful" - that's the point I was trying to make.
qcow2 snapshots were kind of a quick hack, a configuration file seems
more coherent.
