there is no inotify-esque tracking of those files.

What the trigger does is registering the uci file as change source for
the service so that an "/etc/init.d/firewall reload" or an
"reload_config" would trigger a firewall restart in case the
/etc/config/firewall got changed since the last reload.

See package/utils/busybox/files/sysntpd, it does the following to reload
the Busybox ntpd in case any netifd-tracked interface changes:

procd_add_interface_trigger "interface.*" $n /etc/init.d/$name reload

Which translates to:

For any ubus event "interface.*" (e.g. interface.up, or interface.down)
where the value of the event's "interface" attribute is "$n", issue the
"/etc/init.d/$name reload" command.
