Thanks you for the patch! It looks good to me. We can merge as soon as
we have a successful test report.

I heard the Lamobo R1 has design problem that routes packages from the
WAN port to LAN port while the machine is in booting state. This exposes
the internal network machines to security issues. We should be sure to
confirm and document this fact in the manual.

This is not a blocker for us. This is unfortunately the case with most
Wi-Fi chips. We are recommending our users to use a separate Wi-Fi dongle.

This is not related to the build or the board. We are sorting some
issues with FreedomBox auto mounting disks.

It appears that the problem is with finding the /boot partition during
boot. It is unlikely to be a problem with Ethernet (that must be a
separate issue).

During boot, systemd tried to mount /boot because it saw an entry in
/etc/fstab. It should be listed with a UUID instead of /dev/something
device. No device with that UUID was found and so the boot process
eventually failed.

The UUID above looks corrupted somehow. Could you please check the
contents of /etc/fstab in the built image specifically the /boot entry
and confirm that the UUID is same as the UUID of the /boot filesystem
(obtain can be read using dumpe2fs /dev/mmcblk0p1). I use the following
handy script to debug my images:

#!/bin/bash

set -xe

kpartx -avs $1
mount /dev/mapper/loop0p2 /mnt
mount /dev/mapper/loop0p1 /mnt/boot
mount -o bind /proc/ /mnt/proc
mount -o bind /sys/ /mnt/sys
mount -o bind /dev/ /mnt/dev
mount -o bind /dev/pts /mnt/dev/pts
chroot /mnt
umount /mnt/dev/pts
umount /mnt/dev
umount /mnt/proc
umount /mnt/sys
umount /mnt/boot
umount /mnt
dmsetup remove loop0p2
dmsetup remove loop0p1
losetup -d /dev/loop0
