升级弓系统使用pacman，然后复制正确的文件到EFI目录

These scripts will first check for new packages using "pacman -Syy" and will then tell you the number of upgrades available" Then it will ask if you would like to upgrade or not. After you upgrade it will ask if you"re using a UEFI system. If so it will copy the new files in /boot to /boot/efi/EFI/arch/ and rename them appropriately. These scripts require "archey" to display the nice looking arch system info. Place both these scripts in /usr/bin and chmod both of them. Obviously it will only run under root privelages.
