RPI CM4 clone from eMMC to NVMe drive fails due to partition naming

[tkuehne71]

I have a Raspberry Compute module 4 running Ubuntu server 22.04 LTS from the internal eMMC flash of the CM4. I am trying to clone from the eMMC flash memory of the compute module to an NVMe drive that is attached to the PCIe slot and subsequently boot and run the system from the NVMe drive.

The device is enumerated as "/dev/nvme0n1", and the two partitions would appear as "/dev/nvme0n1p1" and "/dev/nvme0n1p2".

Rpi-clone does not appear to be able to support this naming, since it only wants to add a single digit number for the partitions, i.e. it is trying to name the partition as "/dev/nvme0n11" or "/dev/nvme0n12".

Is it possible to explicitly name the output partitions to support this naming scheme?

Here's what lsblk shows:
mmcblk0 179:0 0 29.1G 0 disk ├─mmcblk0p1 179:1 0 256M 0 part /boot/firmware └─mmcblk0p2 179:2 0 28.9G 0 part / mmcblk0boot0 179:32 0 4M 1 disk mmcblk0boot1 179:64 0 4M 1 disk nvme0n1 259:0 0 119.2G 0 disk ├─nvme0n1p1 259:1 0 256M 0 part └─nvme0n1p2 259:2 0 119G 0 part

Here's the output of the failed run:

rpi-clone /dev/nvme0n1 -v

Target disk nvme0n1 ends with a digit so may be a partition.
rpi-clone requires disk names like 'sda' and not partition names like 'sda1'.

Continue anyway? (yes/no): yes

FYI

raspiBackup recently got support for NVMe on CM4 ;-)
