Hi.

LuCI Trunk and the 0.9 branch offer hooks for that:

 on_init              | Before rendering the model
 on_parse             | Before reading any form values
 on_before_commit     | Before writing the config
 on_after_commit      | After writing the config
 on_before_apply      | Before restarting services
 on_after_apply       | After restarting services
 on_cancel            | When the form was cancelled

Use them like this:

- -- >8 --
m = Map("foo", ...)
m.on_after_commit = function(self)
        -- all written config names are in self.parsechain
	local file
	for _, file in ipairs(self.parsechain) do
		-- copy "file" ...
	done
end
- -- 8< --


HTH, Jow
