Yeah, try to use CentOS when a vendor specifies Red Hat (all sorts of hell). So, I pay Red Hat. I did have a vendor that we didn't go with that specified Fedora but not Red Hat. The world is a bit weird, and I have no clue why that would make sense.

I haven't been screwed by MTier, but I would prefer a world where syspatch is done and working. So, I would guess the single item will fall away for you. Just a question of time I guess.

Although, if you don't read the patch notes for a lot of these OSes, you will get bitten in the butt. I got hosed by a combination of Microsoft and Oracle once. If I had read the notes I could have saved myself a weekend of WTF.
