It's not, although I would admit that it's painful to learn. I spent my fair share of time learning it, and can now understand what's wrong with my configs in a split second when it doesn't work. Overall it's faster and easier to search with than apt, from my (very small, I admit) experience with apt. The dependancy system works really well, even when messing around with upgrades/downgrades/uninstalls too.

And I admit that a few years ago I would rank apt as much better than yum. Matter of preference / habit I guess.

I agree about Yum as of RHEL7, but dnf/yum4 are actually quite good in my experience.

Could you expand on this or share pointers to any articles/posts on this?
