I have three machines that run OpenSuse, my desktop and two laptops (well, one laptop and one very low-end IdeaPad). On my desktop, I run into the same problem as you; I think my system partition is just a little small. On the laptops, I have not had any trouble with snapshots. I do like the idea, though - if an update breaks anything, just roll back to the last working state. Windows did this 15 years ago, it was about time Linux distros started catching up.
