CloneZilla seems to skip EF02 grub partition

[Redsandro]

This guide helped me out when I restored a CloneZilla image from a (now broken) SSD M.2 device to a (new) NVMe M.2 device. The latter would only boot over EFI.

Be advised that upon creating a new CloneZilla image, the EF02 partition is not backed up.

I don't know how this works. I didn't know Grub writes data between the partitions, and I don't know if that would have been backed up with CloneZilla when the storage was still MBR. But I do know the EF02 partition is not in the list of backed up partitions.

So maybe there could be a caveat or footnote to indicate that upon restoring a backup made using "intelligent" tools like CloneZilla, ocs-sr, or perhaps some of the commercial tools out there, may skip the raw unformatted EF02 partition used by GRUB, and after restoring a disk image, one would be required to redo the grub installation from a chroot environment, e.g. the following steps:

• 2.3. Mount the remaining filesystems
• 3.1. Execute a shell in a “chroot” environment
• 3.3. Mount remaining disks
• 3.4. Install grub-efi

There are a lot of elements here I don't fully understand, but perhaps someone who understands Grub better can consider if this issue is moot or good.
