Maciel: Because your distro should be cool

-100 points do not pass go, go immediately to a.s.r.

Now, sure, yum allows you to easily "yum history undo" and it will work just as well moving back 3 months of package updates instead of just the last one or two transactions ... but that doesn't mean it's a good idea, even if the technology is perfect all the time.
Anyone advocating that people should regularly do that kind of thing needs to take some little green pills, IMNSHO.

There's also this wonderful gem (in the comments):

As I'm sure the "author" doesn't know, rpm also tracks "every single file" (and dpkg could kind of do it, last I looked). As for "the stability" of using a distro. with few users, one of which is very loud and mis-informed, that and a dollar will buy me a donut.

And, yeh, I've used an rPath based distro. (a few years ago) ... and it was interesting at the time, but time moves on and I know rpm/yum has mostly caught up, in the areas it was behind.
