Sysfs, Udev, Proc, Devfs...what the frick?


Alright, I've gotten lost now. Someone who knows what they're talking about needs to explain sysfs, udev, procfs, devfs...from what I can see sysfs and udev are a new 2.6 deal, while devfs is history and procfs is still used? So what the hell is the difference between sysfs, udev, and procfs? And what should I do with my static /dev files? BTW, I can't get udev to work anyway...but I figure its because I don't know how it works. I'm just a bit pissed at the moment about the lack of documentation on all these. I've spent a lot of time searching and I've found jack. Even the hotplug site says to set things up should either be done by your distro or done with an rpm. Well what about those of us who want to hack things a bit and install stuff from source? Anyway, someone explain to me what I need and how it works! I'm extremely frustrated...

devfs is a virtual filesystem which create device on the fly when needed. procfs and sysfs are vfs used for getting infos about the system. procfs is call to disappear and will be replaced by sysfs. You can find documentation in the kernel source tree: <src_dir>/Documentation/filesystems
