I'm still a bit puzzle by the mechanism here. In my opinion it would
make sense to test if chg works in all case, that way if someone
introduce something that break the basic chg principle we would detect
it in all cases.

Having this running only if --chg is specify defeat this principle. Are
we building (and making available) chg in all case? or only when we use it?
