Update grub on $Source - maybe

Hello

Mine is probably a way-out-there scenario, but may be worth mentioning.

I have a second disk in my Ubuntu desktop system which I keep updated as an 'emergency backup.' This is easy, thanks very much to your script. My grub entries on the main disk ($Source) include one for the cloned Ubuntu ($Target), and so I can boot the clone and check that all is well - without having to go to the bios to change boot drive.

After I update a kernel on $Source, I use clone-ubuntu-thiggy. It copies the new kernels to /boot on $Target and the new grub it creates there lists the new kernels from both $Source and $Target - which are both the new ones.

However, grub on $Source still has the old kernels for $Target listed in its grub.cfg, and so $Target won't boot from its entry in the $Source boot menu.

This is easily fixed by running grub-update on $Source, and I've added a line in the script to do that. I don't know if this would be useful for anyone else.

Exclude some dir

You can add an option to exclude some dir on cloning process.
I make it mannually, adding the dir I want to exclude to rsync command and remove the size check.

Failure to put files in EFI partition

System boots from original disk with UEFI
From /etc/fstab:
...
UUID=A346-6D27 /boot/efi vfat defaults 0 1
...
This line is repeated in cloned (target) /etc/fstab .
I created a 100MB partition at the beginning of the target disk, however it remained empty.
What should the contents of this partition be? And what other changes (e.g. in the target /etc/fstab) should there be?

Any additional information I can provide, my email is [email protected]

Cannot read partitions from disk with NVMe disks

Bug

While trying to clone data from an HDD (regular disk partition syntax /dev/sdbX) to a new M.2 SSD (NVMe, disk partition syntax being /dev/nvme0npX) I had an error where fdisk was not able to list the partitions on the target disk.

Cause

After digging a bit in the script, I managed to get it to work by replacing the following line by this one:

    TargetDisk=$(echo "$TargetRootDev" | sed 's/p[0-9]\+$//')

This way instead of trimming only the number at the end of the partition to retrieve the disk name it also trimmed p.

I guess it would probably be more resilient if the updated regular expression was /p\?[0-9]\+$// instead to also handle a regular disk partition syntax.

If you want I can open a PR for this and you can have a look at it when you have some time!
