During alpha or maybe early beta, I noticed that grub2-mkconfig would use 
different syntax when called by anaconda with the installed system chrooted, vs 
called directly. The former (installer) produced grub.cfg used e.g. 
root=/dev/sda2, whereas a grub2-mkconfig once booted from sda2 would produce 
e.g. root=UUID=<uuid>. So it's possible something else is going on, because I 
think grubby just does uses an existing boot entry as a template for the new 
kernel entry.
