Can You test if adding here "ethernet1 = ð0;" would set the MAC address (also
add eth0 label to ethernet node), if yes we won't need to add it in
06_set_iface_mac.

Small stylistic note. Usually if we include dtsi with already specified nodes,
we don't alter them here, instead operate on labels set in dtsi. For example
this node would be: "&rtc { status = "disabled"; };" outside of the root node.

Since the partitions are defined, why exporting the full flash,
is that useful/used for something?

You can remove: kmod-usb2, kmod-usb3, kmod-usb-storage, kmod-ata-core,
kmod-ata-marvell-sata, kmod-fs-f2fs, kmod-fs-ext4 - all are already enabled in
kernel config.
Does this NAS in factory firmware use XFS of VFAT for formatting HDDs? If no
please
remove.
