I don't like the idea of popping up yet another dialog box for someone
to click a button so things can proceed. I am going to make sure that in
the s390x installation guide, this behavior is mentioned specifically so
that it won't (read: shouldn't) be a surprise.

I am even ok with amending the text on the main hub to say, "We won't
touch your disks until you click 'Begin Installation', with the
exception of DASDs requiring dasdfmt." (Only for s390x installs of
course.)

To me it seems that if you have selected a disk that you want to use
during installation, it's implied that you want to render it *usable*
such that anaconda can actually utilize it.
