Controlled rollouts can be done with selective classes.
groups:
stage1 = ( foo bar baz )
stage2 = ( quux )
stage3 = ( some other machines )
rollout = ( stage1 stage2 )
editfiles:
rollout::

You just add the machines that you want rolled to the class as you go along.

I think you're missing the point of convergence. It's not a "one-off", it's
"does this need to happen, or doesn't it?".
Test if the new utility isn't installed, and then install it. It's a
"one-off" as long as far as you're concerned, because cfengine is converging
on the wanted configuration of your system.
