update-grub

Regenerate the GRUB menu on Debian systems

Debian and Ubuntu wrapper around grub-mkconfig that writes a fresh /boot/grub/grub.cfg using the current kernel and /etc/default/grub settings. Run it after kernel updates, fstab changes, or editing GRUB options. It must run as root and prints the kernels and initrd images it detects.
