Sorry John, I don't think OOB is fixable without first fixing yum as
imgcreater uses yum to resolve dependencies and install the rpms. The
problem is that yum deduces what arch yum is running on by calling uname
and offers no way to override that variable[1]. The PTB didn't view this
behaviour as a bug, which later cropped up in other places in Fedora
like anaconda[2]. Even Martin felt the effects of this decision[3].
