what a kind, considerate and genuine soul...
- trigger script
i'm thinking, '/etc/watchcat.user' ( aka /etc/udhcpc.user )... short term, provides the most extensible, modular framework.
probably as a list though... i.e. ' list user_script 'A''... the only downside of this method is lack of luci management...
suppose an additional built in sample/daemon script could overcome that... something like ... 'option watchcat_script 1'...
- trigger hotplug events
in or out of the script/s above 'option hotplug_ifaceevents 1' or similar...
