Yocto uses this feature in a number of configurations; it creates an archive "/etc/dev.tar" on the first boot and, if this archive exists during the next boot, it gets extracted and most of the coldplug events are filtered. Only if the archive does not exist a full scan is performed. This accelerates booting in static configurations, but also causes problems because cold plugged devices may not get detected (see http://www.denx.de/wiki/view/ELDK-5/FrequentlyAskedQuestionsAndAnswers#Missing_Device_Files_for_Cold_Pl) > == Scope == > # Implementation: 2 weeks > # Benchmark creation: 1 week > # Adapt to community feedback, tests and upstream: 2 weeks This appears to be way to high. All that needs to be done is using a Yocto based file system :-) Alternatively copy the "udev-cache" recipies from Yocto resp. openembedded-core.
