Doesn’t systemd have the ability to do this as well with unix sockets?

I don’t recommend using the shell on routers for day-to-day management. Instead, consider using a network configuration management system like rconfig. I’ve used RANCID in the past, but I suspect something more modern like rconfig will be useful to you.

I subscribe to [email protected] which helps. Other than that I look for mentions of other communities in comments, similar to how I used to on reddit.
