Well, but it'd be wrong anyway. If you look at how the combo updater works: It does _not_ replace components that weren't updated. You see: I'm not sure _why_ the delta updaters so often create problems. But comparing my call to use combo updaters to archive & reinstall is totally wrong, lurk. I'm not sure where you want to drive this discussion. It's wrong.
My suspicion is that what we really have here is a bad case of
confirmation bias and that is all. I have been listening to the mantra of "repair permissions + combo-install" for years and I still have not found a better explanation from its proponents than the Mac equivalent of sprinkling magic pixie dust. To be honest I don't actually care if it works or not, I care that it is offered as a solution to hapless users with no notion of if or why it will be beneficial.
You yourself said that "[you are] not sure _why_ the delta updaters so often create problems." One of the possible mechanisms that I heard for why this was is that the combo updaters in some way clean up the already installed updates, through fixing their permissions, replacing damaged files, or just tickling them in the right way in the amalgamated post-flight script. That is why I said that in some way running the combo updater is the
moral equivalent to an archive and install, it is just resetting large hunks of the system. Keep in mind that this idea is based on a generous assumption that the combo updater was actually doing something more than the delta update. If, in fact, we have the case that the combo and delta should operate exactly the same because the combo does not go over and above, well isn't that even more damning of your position. Because then you are only saying that there have been more random errors in one version than the other--combo updaters are better out of pure luck and nothing more. (Assuming that there is even a measurable effect here at all, I really am more inclined to believe confirmation bias at this point myself.)
As far as what I am trying to do by arguing this, well I am trying to make the world a better place
I don't know what it is about the odd intersection of events in life but I have been coming up against lots of quackery in many contexts of late. This little bit of Mac homeopathy just happened to come along and I thought I might try to take a stand on this one. It certainly is not anything against you fryke, your tone sounds a bit like you think I am attacking you personally. I am not.
I am also not against this on a philosophical level, a sane explication would even get me to go the combo route. Even an explication like "Bob, the engineer who packages up the updaters, has a bit of a drinking problem and he tends to do the combos in the morning when he is more sober." would be just fine by me. What I don't like is the faith-based approach to computer science.
OK I'll shut up for a bit now
