Pinebook Pro/Use NVME as Root

Table of content

Directions on using the Pinebook Pro's NVME as a root partition and the EMMC as

Assumptions

  • You have an NVME drive installed and formatted with a single EXT4 partition

  • Running Manjaro Arm or ALARM. Untested, though Debian may work the same as well. This process relies on the existence of /boot/extlinux/extlinux.conf

Mounting the system

mount /dev/nvme0n1p1 /mnt
cd /mnt
mkdir dev sys proc mnt

Copying root files

Use rsync to transfer the files. This excludes pseudo file systems. 

rsync -aHxv --numeric-ids --progress /* /mnt --exclude=/dev --exclude=/proc --exclude=/sys --exclude=/mnt

Changing the root to nvme

Rename the boot folder which was copied to the NVME. This isn't needed. Edit your extlinux.conf file on the EMMC, then change the setting for the root partition path. 

$ mv /mnt/boot /mnt/boot.old
$ vim /boot/extlinux/extlinux.conf

# Change "root=LABEL=ROOT" to "root=/dev/nvme0n1p1"

Fix for read only boot partition error

If the boot partition is "read only", you can remount it with rw permissions as so: 

$ mount /dev/mmcblk1p1 /boot -o remount,rw
