This is probably going to be a dumb one, but I'm going to ask anyway. Yeah, I know, never stopped me before.
After I flash an OpenWrt upgrade and install my usual packages (some of which I'm not using - I just want them there in case I later do) with no issues or warnings, I next get a lot of "Configuring [package name]" lines in my terminal window. Very occasionally after one of these lines, I get "NNNNNN WARN : Service section disabled! - TERMINATE" in my terminal session. I'm seeing it after configuration messages for the following packages: kmod-ipt-conntrack-extra and luci-app-ddns on my AP's, and iptables-mod-ipopt and ca-bundle on my EdgeRouter.
Everything I'm using and set up is working just fine. Are these warning messages just OpenWrt telling me I haven't set up the input for these packages in the configuration files yet? If so, I'll ignore and move on.
