What is the intended behavior of mediacheck on FAIL (either on Install or Live
images)? In doing a test install in a KVM guest using the "check" boot parameter
on an Install image, the mediacheck FAILed (which happens frequently in KVM,
although not reproducibly) but instead of at least prompting for what to do, it
just continued as if nothing happened. This is bad since would force people to
constantly watch the mediacheck progress to catch a FAIL and even then they
might not see it if it goes by too fast. The original mediacheck showed a screen
with PASS or FAIL and you had to tell it to continue. It's okay to proceed
automatically on PASS but not on FAIL. I tried deliberately corrupting Install
and Live images by replacing a few MiB at the end by zeroes and it always drops
to a dracut prompt, which did not happen with the original KVM install.
