What do you do with the grub

[CicadaSeventeen]

Hellp,
I wonder how can you make grub into such format (openSUSE-like interface)? Is there any patches (I do not find them in files)?
Besides, how to set default kernel? GRUB_DEFAULT not works here.

Hi there, sorry for the slow reply.

It has very few modifications to the vanilla Debian defaults, it mainly just included a background image. You can see what gets used in /config/bootloaders/grub-pc/
