When reading this documentation, I came across several configuration options that are not present in dnsmasq --help nor in the online man page of dnsmasq. As explained in the doc, there is no CLI man page in openWrt.
2 examples of the missing options are nonwildcard and notinterface.
So I am guessing the dnsmasq on openWrt is actually a modified version of dnsmasq, specific to openWrt.
How can I access the list of exhaustive options, and their explanation for the processes on openWrt, other than in the openWrt documentation? I have developed a habit of checking CLI usage with --help or man because I know wikis can sometimes get out of date, hence why I am asking,
Search for the UCI option in the dnsmasq start script, /etc/init.d/dnsmasq, where you can find its translation to the dnsmasq CLI option. They do not necessarily resemble each other. For example, nonwildcard maps to --bind-dynamic.
