   What is this insmod line? where can I find an example? I was thinking   
   there should be someway, but I could not find it. In my search I'm   
   finding way to much I don't understand. I see things like btrfs grub   
   module won't fit in the mbr. And btrfs-grub. By the way, I still use   
   legacy-grub.

   I was thinking it would not be a problem, but now I won't know until I   
   see it. Maybe my system is not a good candidate for btrfs.
