I set the immutable attribute on resolv.conf following section 2.1 in https://wiki.archlinux.org/title/Domain_name_resolution
That's what I did for many moons. Eventually I converted all but two (a non-multiboot laptop with wireless, plus my sole desktop installation using DHCP) of my then currently supported installations from whatever they were using to systemd-network. In the process I'd run systemctl list-unit-files | grep solv then disable and mask anything returned that wasn't already. Nothing has been touching any of the copies of my template resolv.conf file, last written 2020-11-30, that all installations (but two) have had in their /etc/s ever since. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
