[PATCH] udev - next round of udev event order daemon
Here is the next round of udevd/udevsend: udevsend - If the IPC message we send is not catched by a receiver we fork the udevd daemon to process this and the following events udevd - We reorder the events we receive and execute our current udev for every event. If one or more events are missing, we wait 10 seconds and then go ahead in the queue. If the queue is empty and we don't receive any event for the next 30 seconds, the daemon exits. The next incoming event will fork the daemon again. config - The path's to the executable are specified in udevd.h Now they are pointing to the current directory only. I don't like daemons hiding secrets (and mem leaks :)) inside, so I want to try this model. It should be enough logic to get all possible hotplug events executed in the right order. If no event, then no daemon! So everybody should be happy :) Here we see: 1. the daemon fork, 2. the udev work, 3. the 10 sec timeout and the skipped events, 4. the udev work, ..., 5. and the 30 sec timeout and exit.
