[-- Attachment #1 --] Hello all, With so much discussion about updating boot, I feel confused about the correct procedure of doing it. Like being said there are a "24.3. Updating Bootcode" in Handbook (WIP) that points to some important manuals. There are 3 places where boot loader are: ESP (EFI System Partition): 1 - (/boot/efi)/efi/boot/bootXXX.efi (default location) 2 - (/boot/efi)/efi/freebsd/loader.efi (FreeBSD reserved area) Operating System: 3 - /boot/loader.efi For what I've read we should: - backup: `cp /boot/efi/efi/boot/bootXXX.efi /boot/efi/efi/boot/bootXXX.efi.bkp` - update: `cp /boot/loader.efi /boot/efi/efi/boot/bootXXX.efi` In this example we have a /boot/efi mount by the system, "/dev/XXXpN on /boot/efi (msdosfs, local)". What about (/boot/efi)/efi/freebsd/loader.efi (reserved area)? Is necessary to backup and update it too? Thanks, -- Nuno Teixeira FreeBSD Committer (ports) [-- Attachment #2 --] <div dir="ltr"><div>Hello all,</div><div><br></div><div>With so much discussion about updating boot, I feel confused about the correct procedure of doing it.</div><div><br></div><div>Like being said there are a "24.3.
