+The supplied configuration provides two functions, `bootfde` and `bootimg` that simplify the two previous examples into:
+
+    menuentry 'darkstar: full disk encryption' {
+      bootfde darkstar-root
+    }
+
+    menuentry 'darkstar: preloaded images' {
+      bootimg darkstar-root

+Create a bootable image

+
+    grub-mkrescue -o output.img /tmp/bootless

+Record the image into the USB stick

+*WARNING!* This will irrevocably replace the contents of your USB stick.

+Pay attention to get the right device. If your USB stick is attached to
+your computer and reachable through `/dev/sdb`, you just have to run

+    sudo dd if=output.img of=/dev/sdb
