Sure. But do we now exchange this for all the broken systems where replacing root with the snapshot after the transaction? And are we sure the number of broken systems will actually shrink with this change? (and can you prove that?)
That question implies to never dare testing a different approach than what is currently in use - as you will not be able to guarantee that a new idea as such works better than the old way of doing things without testing it.
Well, but it must at least be sound if it causes work for others, right? So, proving might be a bit too harsh indeed, but the transactional updates (at least as I understand them right now) seem a bit dubious in that they replace a certain set of problem with other (IMHO worse) problems. How many of the problems solved by transactional updates are actually solved by the required reboot (or could be solved by that alone), and not by the installing-into-snapshot aspect? Ciao, Michael.
