Grub-install question

Support
1

reeding here:
A normal user will install grub only once. This happens when our installer Calamares does it for you. If you update the grub package via pamac or pacman you won’t update grub itself in your master boot record (MBR) or UEFI. This means you may still run an outdated grub on your system to boot your OS. Some grub updates however have security fixes which need to call grub-install.

does that means I’ve to do grub-install from live iso every time grub gets updated?

No

This means

  • We do not update grub (the binary) because your system may be customized some way we do not know about. :see_no_evil:
  • In almost every case it is not necessary to change the binary of grub, so we avoid the risk :upside_down_face:
  • If you think you need to update the binary, this is your own risk :man_shrugging:
  • Grub can be reinstalled from within a running manjaro installation
  • If grub does not boot, because you messed it up, you will neeed to boot via USB
  • grub config files will be updated automatically :ok_hand:
