EFI System partition

[spetrillo]

So a very interesting tidbit of information...

If you build PVE with Grub then there is an EFI directory under /boot/efi. If you build PVE with SystemD then there is no directory under /boot/efi. Thats not what I would have expected. It looks like when building with SystemD the directory structure is under /sys/firmware/efi.

Why is /sys/firmware/efi write protected? I cannot drop my tools there? I am wanting to drop my Intel bootutil tool and flash image, so I can update the flash on my Intel I350 network adapter.

like I said last week - "/sys/firmware/edi/efivars is how the kernel exposes EFI variables, it's not a place where you can store anything other than variable values".

if proxmox-boot-tool manages the boot aspect of a PVE system, then the ESP(s) are not mounted unless needed. you can manually mount them (their UUIDs are stored in /etc/kernel/proxmox-boot-uuids)
