Well, from a technical perspective, which ref is to be updated is an option that is valid _only_ under no-checkout mode, and no-checkout mode could be using HEAD, so I think you would need two variables. One for "what mode are we running", and the other that is only valid under "we are in no-checkout mode" that says "we update BISECT_HEAD". If no-checkout mode _never_ updates HEAD, because the normal mode _always_ updates HEAD, you could reduce them into a single variable (i.e. if we are updating HEAD then we are in normal mode, otherwise we are in no-checkout mode). I actually have a mild suspicion that the no-checkout mode may turn out to be too confusing for people if it by default updates HEAD, and we may want to have it update something that is not HEAD by default (or forbid --update-ref from specifying HEAD), so if that turns out to be the approach we are going to proceed, we _might_ end up needing only one variable, but I do not think we know it just yet. At least I don't. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
