Do we really have /tmp/ access at recovery? Never tested, downloading the tarball to test.

Any reason for it not to be a separated script? If separated, also make sure to add a header with copyright and such.

+network_settings_bak=/data/nm_connections

I'd prefer to use a common directory for backups, like /data/ubuntu_bak or similar, so we know where to find the files in case of a failure when flashing the image.

Rest looks fine, creating an image to test it.
