I'm working on XBMCLive (Ubuntu together with live-build 3.x) and using a config with grub2 as bootloader and iso as binary image. When setting the debian-installer to true the image creation fails. It seems that there's a dependency in the lb_binary_debian-installer
to use the older grub versions. It would be very nice to have permanent fix for this. I'm using the code below to temporary fix this issue.
