2015-11-26 Rawhide nightly boot.iso's completely fail to boot. With a bit of research we easily see the cause: Failed to execute /usr/lib/systemd/system-generators/dracut-livenet-generator: Permission denied /usr/lib/systemd/system-generators/dracut-livenet-generator failed with error code 1. this script was added recently: https://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=a455ad1c272170664022b4cc0a160fe9c737d993 but was set to the wrong mode (0644 not 0755). This is an automatic blocker for F24 Alpha: "Complete failure of any release-blocking TC/RC image to boot at all under any circumstance - "DOA" image (conditional failure is not an automatic blocker)" https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process#Automatic_blockers Attaching a patch.
Created attachment 1099486 [details] patch against upstream dracut git master to fix the bug
