udev - a userspace implementation of devfs For more information on the design, and structure of this project, see the files in the docs/ directory. To use: - Edit the udev.h file and replace the following variables with values that make sense for your system: #define SYSFS_ROOT "/sys" #define UDEV_ROOT "/home/greg/linux/udev/" #define DEV_FILE "/dev" #define MKNOD "/bin/mknod" The only value most people will have to change is the UDEV_ROOT variable, as I doubt you really want device nodes to be created in my home directory :) - Run make to build the project. - Make sure sysfs is mounted. - Point /proc/sys/kernel/hotplug at the location of the udev binary that is created. Then plug some block devices in, or other types of devices that create dev files in sysfs. An easy way to do this, without any hardware is to use the scsi_debug module to create virtual scsi devices. - Watch as the nodes get created and removed. Yes this is a really rough first cut, I know. It's mostly a proof of concept that this can actually work. See the TODO file for a list of things left to be done.
