I've read it, in fact, it's what I was reading when I replied to your
message. I don't believe it goes against anything I said.

I don't think that question makes sense, exactly. the gpt system does
not *have* an mbr (well, technically it does, but its sole purpose is to
prevent things which expect to see an mbr from screwing up gpt): the mbr
is the defining feature of the 'old' msdos system. you can talk about
'mbr' instead of 'ms-dos disk label' if you want, the two are almost
interchangeable. The only way you could 'use mbr' instead of 'using gpt'
is to not format the disk as gpt at all, and anaconda does not allow you
that option, at least interactively (not sure if you can do it via a
kickstart).
