# Reinstall grub after a package update, and update the /boot/grub/grub.cfg file

# This hook is intended to prevent one's system of becoming unbootable after a package upgrade

# Depending on how you installed grub, what shell you use and what is your ESP, adjust this file accordingly!

# Also, a pacman update will probably overwrite any customizations done to the /etc/default/grub file and files inside /etc/grub.d/
# In this case, reimplement your customizations and re-run the grub-mkconfig command
