Embedding config file while compiling grub-efi binary.

[mbusb]

Hi all,

I am on Manjaro with up to date packages. Downloaded grub2 source directly
yesterday and trying to compile for generating a gpt compatible grub-efi
binary. Since I have all my distros in a custom directory of my pendrive, I
would like to check if grub.cfg path exist and load the configuration file
accordingly.

I found that embedding configuration file during boot time is the correct
way to go and I have included following code in the custom embed.cfg file:-

 for dev in (*); do
  if [ -f "$dev/customdir/grub/grub.cfg" ] ; then
    configfile "$dev/customdir/grub/grub.cfg"
    break
  fi
done

Then I issued the following command to compile the binary:-

$./grub-mkimage -d ./grub-core -o bootx64.efi -O x86_64-efi -c ./embed.cfg
-p ""  $(find . -name '*.mod' | tr '\n' ' ' | sed -e 's/\.mod//g')

Since I was not sure what all module required for successful booting of
embedded configfile, I included everything.

Now the real problem comes when I boot the usb on my laptop, it gives some
error (which I can't read properly due to faster disappearance) and lands
in to grub shell. Once I am in to shell, I executed every line and it
successfully booted my custom config fiel.

My question is, where did I go wrong? Why does grub goes to shell even
though I have not supplied any menu entries in embedded config file?

Any help is appreciated.
