[OpenWrt-Devel] /sbin/hotplug-call iface event never fired

I found this problem while trying to make ddns work.

This command updates ddns:
# ACTION=ifup INTERFACE=wan /sbin/hotplug-call iface

But: 1) reboot would not update ddns; 2) if ip address changed in a
day, ddns would not update;

Thus it seems the hotplug event only happens if I invoke it manually.

So, now what? What to do next to check the problem? Thanks.
