Comment I'd say the same thing for any OS (Score 1) 706
Upgrades are a nice idea, but they are asking for problems. Sure, sometimes they work fine, other times they have strange problems, still other times your whole system blows up.
Happened to one of our students running Linux. He runs Ubuntu on one of his systems. The last two times a major update has come out, he's told it to update. In both cases, the system was totally hosed as a result, and required a reinstall.
I always like the full reinstall option for OS upgrades. It is by far the way to the least amount of problems. I also find it serves another useful purpose: Cleaning out of junk. Many of us (like me) are hoarders and collect data we don't really need. A reinstall cleans all that out. You either back it up, or it goes away.
I just don't get the point in upgrading OSes.
