This has come up from time to time.  One answer is that if we don't
detect something that looks like an MBR and we're doing this (or any
install /boot partition type installs), we should overwrite with a
"real" MBR.  The problem is that this could trample over some other boot
loaders which has been something we haven't been willing to do in the
past.  Maybe we should pop up a warning and default to doing so, but
give a way out if the user knows that they have a valid reason.  Even
though I hate those sorts of things :/
