Description of problem:
Booting from recent TCs/RCs including 17 Beta RC1, the installer no longer offers a mediacheck. I also tried boot options "mediacheck" and "inst.mediacheck" and neither of those do anything. I haven't checked the behavior of live images.
Version-Release number of selected component (if applicable):
whatever is in 17 Beta RC1
I don't know what Will might have in mind for this given the no loader stuff, but I've definitely got it covered for the new UI in F18 if nothing happens for F17.
While on the topic, what is the status of mediacheck on the netinst images? I know it's been gone for a while, but it would be nice to be able to have a Final criterion requiring a mediacheck on all images (netinst, DVD, and live). The current criterion only says "If there is embedded checksum on ISO media, it must be correct." but most people probably don't know how to do an external check.
According to https://lists.fedoraproject.org/pipermail/test/2012-March/106409.html :
If you pass 'check' on the cmdline dracut will run a mediacheck. We may
want to add a menu option for that under Troubleshooting.
I confirmed that this works for both DVD and netinst images (which I thought didn't have a mediacheck any more). I think it would be better to make this default and have a "nocheck" option instead, as Adam suggests in the followup message. In fact I think this should happen for live images as well. Having the DVD, netinst and live images all check themselves automatically could prevent a lot of destructive installation/upgrade failures.
Closing since the mediacheck exists. I might open another bug as an RFE though.
