• GRUB 2 administration: /etc/default/grub, grub-mkconfig, grubby and the default entry

  GRUB 2 is configured indirectly: settings live in /etc/default/grub and are compiled into grub.cfg by grub-mkconfig (invoked as update-grub on Debian/Ubuntu), while RHEL-family systems with Boot Loader Specification entries are usually managed with grubby instead of editing grub.cfg by hand.
