Where is the source code that modifies GRUB during use of the graphical installer?

@trusktr

that modifies GRUB during use of the graphical installer mentioned here?

I don’t see what you’re talking about in the link you’ve linked. I see nothing mentioning GRUB there.

The graphical installer is calamares, and the source code is here.

Thanks, that’s it. I meant to link to the section that mentions the installer, I didn’t mean to imply it mentions GRUB there (updated the OP).
