Raspberry Pi OS • Re: Static IP with Bookworm

It is sad even the online rpi os manual doesn't just reference your solution.

It is not surprising that i doesn't. It is an old, outdated way of managing networking.

Using Network Manager is the current method for Raspberry Pi OS. Use the nmcli or nmtui commands to set up connections.

At least the "old, outdated way" did not insist on launching wpa_supplicant ... on a B+ that has no wifi
[EDIT: OK my bad, wpa_supplicant.service is enabled separately.]

I absolutely do not want NetworkManager or anything like it on the Pi I'm currently rebuilding because it is going to be the DHCP/DNS server for my network. It will be the fixed point that facilitates the easy life for the other hosts. Is such a role thought inconceivable?

There is no defensible rationale for having a running config daemon for a static config that can be brought up with 3 pithy lines of bash even without the old-skool ifup scripts. It just gets in the way and wastes cycles (did I mention B+?)

Also for this server-role I'll use dnsmasq, but I note that there are dnsmasq-related config dirs in /etc/NetworkManager/ - I don't know why, and I'd much rather never have to learn why, especially not the hard way when it collides with my own usage of it.

EDITED TO ADD:
I feared there would be a lot to unpick, but it's not too bad. A key point is that Bookworm has removed the old functionality but it is still available (for now?) in the ifupdown package.

So, steps to setup a static wired connection and dispense with NetworkMangler...

1.(The networking service is enabled automatically.)

2. Add settings to /etc/network/interfaces.d/eth0 (adjust for your own network)3. Add your DNS servers in /etc/resolv.conf (ditto)4. Disable unneeded services5. Reboot.

DISCLAIMER: No warranty implied. It worked for me today, it may not work for you tomorrow. NetworkManager is fine really, I use it on many boxes, it's just a bad fit in some scenarios.
