> Hi, I want an unattended installation (just boot from USB, install, and remove USB). I am able to remove all questions during install but I cant customize the grub entries of the live boot. By default is market the option "boot" but I need the  "install" option.

> In the file poky/plain/meta/classes/grub-efi.bbclass I found that the variable GRUB_CFG_LIVE = "${S}/grub_live.cfg" contains the file with this configuration but I cannot find this file. Where the image is built (inside tmp directory) this file exists. I tried  to override the variables "LABELS_LIVE" without success (if I remove the boot option, it also disappears from the installation and cannot boot later).

> Once the image is flashed to an USB memory, the file syslinux_live.cfg exists in the boot partition and if I edit it it works as I want. But this is the bad way, would be great if I can edit it inside yocto build process.

> Anyone knows what recipe should override?

I use:
LABELS_LIVE = "install"

Just before I inherit core-image in my custom image recipe.
