Is -Syy safe?

Consider the following sequence of events:

  1. mirror_2 is synchronized with mirror_1
  2. mirror_1 is updated
  3. user synchronizes his system with mirror_1
  4. user changes to mirror_2 (or just mirror_1 breaks down and mirror_2 is next in mirrors list)
  5. user issues -Syyu

Now the system can be broken, because the user inadvertently updated to an older version and pacman and the update scripts are not designed to cope with this, as far as I know. Moreover, the system might become disfunctional days later, at reboot. Please tell me if I am right on this. If I am, then -Syy might be unsafe at any time and on any mirror. Of course, there is a small probability for this scenario to happen in practice.

The forum is the right place for this kind of discussions, I suggest you open a thread there and report here the conclusions. Also, please use Template:Accuracy for comments in an article like this one. -- Kynikos (talk) 02:30, 11 May 2013 (UTC)
