The udev-lfs set of files is a customization of systemd. In 2012, udev was merged with systemd and a build methodology incompatible with LFS. These files extract the udev code from systemd for LFS. These files are distributed in the form of a tar file available from the LFS file mirrors. The tarball is created with: mkdir /tmp/udev-lfs-$VERSION cp -av * /tmp/udev-lfs-$VERSION tar -jcf /tmp/udev-lfs-$VERSION.tar.bz2 -C /tmp udev-lfs-$VERSION Makefile.lfs - The main LFS Makefile. Builds and installs udev from systemd sources. makefile-incl.keymap - BLFS makefile for keymap and supporting files makefile-incl.gudev - BLFS makefile for libgudev makefile-incl.gir - BLFS makefile for GObject files contrib - Useful rules from debian contrib/debian contrib/debian/83-cdrom-symlinks.rules contrib/debian/write_cd_aliases contrib/debian/81-cdrom.rules 55-lfs.rules - LFS custom rules write_net_rules - Scripts for LFS rules write_cd_rules rule_generator.functions doc - Documentation for LFS installed rules doc/55-lfs.txt doc/README cfg.h - Basic info needed for udev compilation ChangeLog - Log of changes to 55-lfs-rules init-net-rules.sh - A script for establishing persistent network rules before the first LFS boot
