Udev The udev-config tarball contains LFS-specific files used to configure Udev. Unpack it into the Udev source directory: tar -xvf ../&udev-config;.tar.bz2 Create some devices and directories that Udev cannot handle due to them being required very early in the boot process, or by Udev itself: install -dv /lib/{firmware,udev/devices/{pts,shm}} mknod -m0666 /lib/udev/devices/null c 1 3 mknod -m0600 /lib/udev/devices/kmsg c 1 11 ln -sv /proc/self/fd /lib/udev/devices/fd ln -sv /proc/self/fd/0 /lib/udev/devices/stdin ln -sv /proc/self/fd/1 /lib/udev/devices/stdout ln -sv /proc/self/fd/2 /lib/udev/devices/stderr ln -sv /proc/kcore /lib/udev/devices/core Prepare the package for compilation: ./configure --prefix=/usr \ --exec-prefix= \ --sysconfdir=/etc Compile the package: make This package does not come with a test suite. Install the package: make install Udev has to be configured in order to work properly, as its default configuration does not cover all devices. First install two extra rules files from Udev to help support device-mapper and RAID setups: install -m644 -v rules/packages/64-*.rules \ /lib/udev/rules.d/ Now install a file to create symlinks for certain hand-held devices: install -m644 -v rules/packages/40-pilot-links.rules \ /lib/udev/rules.d/ Now install a file to handle ISDN devices: install -m644 -v rules/packages/40-isdn.rules \ /lib/udev/rules.d/ Now install the LFS-specific custom rules files: cd &udev-config; make install Install the documentation that explains the LFS-specific rules files: make install-doc Install the documentation that explains the commonly-used rules files provided by Udev: make install-extra-doc Install the documentation that explains how to create custom Udev rules: cd .. install -m644 -v -D docs/writing_udev_rules/index.html \ /usr/share/doc/udev-&udev-version;/index.html Installed programs Installed libraries Installed directory ata_id, cdrom_id, collect, create_floppy_devices, edd_id, firmware.sh, fstab_import, path_id, scsi_id, udevadm, udevd, usb_id, vol_id, write_cd_rules, and write_net_rules libudev and libvolume_id /etc/udev Short Descriptions ata_id Provides Udev with a unique string and additional information (uuid, label) for an ATA drive ata_id cdrom_id Provides Udev with the capabilities of a CD-ROM or DVD-ROM drive cdrom_id collect Given an ID for the current uevent and a list of IDs (for all target uevents), registers the current ID and indicates whether all target IDs have been registered collect create_floppy_devices Creates all possible floppy devices based on the CMOS type create_floppy_devices edd_id Provides Udev with the EDD ID for a BIOS disk drive edd_id firmware.sh Uploads firmware to devices firmware.sh fstab_import Finds an entry in /etc/fstab that matches the current device, and provides its information to Udev fstab_import path_id Provides the shortest possible unique hardware path to a device path_id scsi_id Provides Udev with a unique SCSI identifier based on the data returned from sending a SCSI INQUIRY command to the specified device scsi_id udevadm Generic udev administration tool: controls the udevd daemon, provides info from the Udev database, monitors uevents, waits for uevents to finish, tests Udev configuration, and triggers uevents for a given device udevadm udevd A daemon that listens for uevents on the netlink socket, creates devices and runs the configured external programs in response to these uevents udevd usb_id Provides Udev with information about USB devices usb_id vol_id Provides Udev with the label and uuid of a filesystem vol_id write_cd_rules A script which generates Udev rules to provide stable names for optical drives (see also ) write_cd_rules write_net_rules A script which generates rules to provide stable names for network interfaces (see also ) write_net_rules libudev A library interface to udev device information libudev libvolume_id A library interface to read volume labels and uuids libvolume_id /etc/udev Contains Udev configuration files, device permissions, and rules for device naming /etc/udev
