That could happen, but seems unlikely because anything corrupt that affects the as-installed boot, would also affect the live boot. But does it result in a crash or does it just result in weird behavior that looks like a bug? I don't know what percent of the bytes of the ISO image is read when booted. 25%? That leaves a chunk of programs and other content in an installation that could have this corruption, and transferred undetected to the target system. And how does it manifest? It's a rare upon rare event, and I expect it will be assumed to be a bug, and maybe we luck out and it goes away following a software update. I've suggested dropping the media check a few times over the years, but always in the context of replacing it with something better, faster, stronger. :P While the risk of dropping the media check is probably low, it's not zero risk. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
