i digged again trough the script and have some ideas: 1) every script probes if itself is 'enabled', so in e.g. /etc/hotplug.d/iface/30-6relay the call is: /etc/init.d/6relayd enabled || exit 0 can we avoid that? maybe if the daemon is disabled via '/etc/init.d/6relayd disable', than the hotplug-file is also hidden? or netifd/procd should not call daemons which are disabled? 2) also every script which needs an action has to fork, e.g. in '/etc/hotplug.d/iface/50-olsrd' we call /etc/init.d/olsrd restart maybe we can just source 'rc.common' once in '/sbin/hotplug-call' and so we can call just 'restart' when we need it? 3) what happens during bootup (where we can see load ~5...10), when all interfaces are fired: for every event we have to restart the whole olsrd-process. i better way would be to 'wait for all interfaces' in one batch and than call it? > By the way, I found an even faster way to deal with that particular > call: https://dev.openwrt.org/changeset/38704 :) 8-) bye, bastian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
