If there is one to be found in the dracut man page, I'm not seeing it. As it is,
one must choose between nohostonly, or chrooting into the clone to regenerate
with correct root UUID.
If your root is on a non-assembled device (like a plain partition), then dracut
(at least for F20) does not store any UUIDs in the initramfs in hostonly mode.
You can check with:
# lsinitrd | egrep '.*requires.*\.device'
and
# lsinitrd | egrep 'etc/cmdline.d/.*\.conf'
Both should be empty for simple partition setups.
