My aim is to be able to backup a running Fedora 21 system to a separate hard disk and be able to boot it in case my current hard disk fails. I achieve this by backing up a LVM snaphot of root, modifying fstab in the backup and editing the grub entries. Furthermore, dracut needs to be set to --no-hostonly. This works in Fedora 19. However, doing the same with Fedora 21 does not work. F21 fails booting; some start jobs are never finished. Why? How do I resolve this?

The boot.log can be found here: http://paste.fedoraproject.org/191595/

Edit: The first hurdle seemed to be disabling SELinux. But Xorg will still not work. I get:

 gdm-Xorg: (EE) systemd-logind: failed to get session: PID 1435 does not belong to any known session

I can login to the console, yes. But gdm will not start due to the X error (see edit).

yeah , I always have selinux disabled ... , to enable selinux you probably need run a command to reassign all selinux permissions

touch /.autorelabel and reboot to relabel the system.
