To test the results, issue: make test. Install the package: make DESTDIR=/ udevdir=/dev install The meaning of the make option: DESTDIR=/ This prevents the Udev build process from killing any udevd processes that may be running on the host system. Udev's configuration is far from ideal by default, so install the configuration files here: cp -v ../&udev-config-file; /etc/udev/rules.d/25-lfs.rules Run the udevstart program to create our full complement of device nodes. /sbin/udevstart Contents of Udev Installed programs Installed directory udev, udevd, udevsend, udevstart, udevinfo, and udevtest /etc/udev Short Descriptions udev Creates device nodes in /dev or renames network interfaces (not in LFS) in response to hotplug events udev udevd A daemon that reorders hotplug events before submitting them to udev, thus avoiding various race conditions udevd udevsend Delivers hotplug events to udevd udevsend udevstart Creates device nodes in /dev that correspond to drivers compiled directly into the kernel; it performs that task by simulating hotplug events presumably dropped by the kernel before invocation of this program (e.g., because the root filesystem has not been mounted) and submitting such synthetic hotplug events to udev udevstart udevinfo Allows users to query the udev database for information on any device currently present on the system; it also provides a way to query any device in the sysfs tree to help create udev rules udevinfo udevtest Simulates a udev run for the given device, and prints out the name of the node the real udev would have created or (not in LFS) the name of the renamed network interface udevtest /etc/udev Contains udev configuation files, device permissions, and rules for device naming /etc/udev
