Looks to me like that was never the aim of sysfs. I haven't checked into sysfs yet but I suspect it is quite different to devfs. > > Why could you develop it so that UDEV could create those > actual device files there also, then most linux > users would not need those horrible scipts anymore. > All that is then needed link from /sysfs to /dev dir. That would take away the ability to have a changeable device naming scheme. One of the main reasons for having dynamic device name mapping system is to map the names from a device detection system to specified (possibly changing) naming scheme. Please don't get me wrong. I like devfs very much and I see it has come a long way since I last used it, but it needs work just to maintain its current functionality within 2.6.
