OK. I have some static nftset entries in /etc/dnsmasq.conf, but for lists that are updated frequently, I want to write a script that generates ready-to-use nftset entries in a file. To reduce the number of flash writes, I wanted to place it in /tmp and include it in the dnsmasq configuration. I already know that all I need to do is copy that file to the /tmp/dnsmasq.d directory.
