Sigh, for the fourth time, I'm not suggesting it. It's not my idea. I'm not going to defend it. I'm relaying a design that was outlined to me by the anaconda devs. The motivation is that there have been multiple requests to make it possible to have a redundant boot chain on native UEFI installs, as you can on native BIOS installs. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
