Not necessarily. If you're doing a baremetal restore, you already have to
have to boot some minimum OS before you can run the fd anyway. What I have
done several times is this:
- boot a plain old fedora rescue CD
- copy the fd binaries, config files, and diskinfo scripts onto it
- recreate the partition tables and filesystems using the diskinfo scripts
- mount the new partitions on /restore
- done a full restore with where => /restore
- reinstall the boot load
- reboot into the newly restored system
Since the boot scripts are designed to come up with an empty /dev and populate
it at runtime, all you have to do is make sure the /dev/ directory exists.
