Talk:EFI boot stub

Automatic updating

@Whxvd I saw that you plan to update the Unified kernel image page with better information on how to automatically update the kernel image on the ESP. I found that this page is even more lacking in information regarding that. There's only a short tip:

pacman will directly update the kernel that the EFI firmware will read if you mount the ESP to /boot.

Since UKI and EFISTUB are somewhat related, would you be able to look at this page as well and add anything you find useful? Thanks! Rua (talk) 12:23, 15 September 2024 (UTC)

Hi @Rua. I did use the EFI stub boot method with efibootmgr in the past. And I can confirm that the short tip is true: The filename of, e.g., the kernel image remains the same (e.g., /boot/vmlinuz-linux with the standard linux package). The same goes for microcode and initramfs. So, as long as the ESP is mounted to /boot, everything is and will remain fine when using this method. At boot time, the EFI or EFI boot loader always just picks up the latest kernel image, initrd, and microcode installed to /boot, without any need for further action. I never had problems when using this method, and neither found EFI boot stub lacking of clarity. So I'll leave it as is. Whxvd (talk) 06:29, 9 October 2024 (UTC)
