Fedora 25 - Change grub timeout

Recently I wanted to speed up system boot by decreasing GRUB timeout.
I've changed it from 5 to 0 seconds so at the moment GRUB doesn't take 5 seconds
before the system boots. It's a very simple operation:

  1. Edit GRUB configuration file - /etc/default/grub
  2. Change GRUB_TIMEOUT value from 5 to 0
  3. Rebuild GRUB.
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Done.
