There seem to be many many many options, which is why I am asking.
I do not wish to install Python on anything other than the control node, certainly not on the router.
But I'd like to be able to do the basics, over a serial connection such as setting the interface IPs, VLANs, trunk ports and firewall config, package installation, overlayfs, if that helps with library recommendation.
Thank you,
