From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.4; Linux) KHTML/3.4.1 (like Gecko) Description of problem: mkinitrd does not copy udev *.rules to the initrd, so if the finding the rootfs relies on udev rules, booting cannot proceed. I encountered this while making a bootable cdrom from fedora rpms, but there may be more scenarios. I don't think it can happen on a "normal" installation. Version-Release number of selected component (if applicable): mkinitrd-4.2.15-1 How reproducible: Always Steps to Reproduce: mkinited ... Actual Results: initrd does not contain /etc/udev/rules.d/*.rules; if the rootfs is on /dev/cdrom (or usb drive, or ...), the root filesystem cannot be mounted. Expected Results: initrd contains /etc/udev/rules.d/*.rules Additional info:
initrd doesn't use udev, and probably won't do so in the future.
