[Trisquel-users] Re : GRUB2 GUI?

[magicbanana]

Notice that the most common things you want to change are not in  
/etc/grub.d/*. They are in /etc/default/grub. This file, whose content is  
commented, is pretty easy to change. It simply is a list of Shell of  
variables to instantiate. As for listing the installed operating systems,  
'sudo update-grub' does a good job (at least it has always worked for me)...  
and it does not write in /etc/grub.d/* either. It writes in  
/boot/grub/grub.cfg.
