<title>Introduction to Udev Extras</title>
|
|
|
|
<para>In 2012, the <application>Udev</application> code distribution was
|
|
merged with <application>systemd</application>.
|
|
<application>Systemd</application> is a set of programs that replace the
|
|
<application>SysVInit</application> package used by LFS and is much more
|
|
complex. It is not compatible with the LFS bootscripts and has many
|
|
problems and few advantages for most LFS users.</para>
|
|
|
|
<para>The procedures below extract libraries and programs from the systemd
|
|
sources that could not be built in LFS due to library dependency
|
|
issues.</para>
|
|
|
|
<para>Unlike any other package in the BLFS book, there is no set version
|
|
of <application>systemd</application> specified to download. Several version
|
|
updates to LFS and BLFS means there are probably many different
|
|
versions of <application>Udev</application> on the platforms that BLFS is
|
|
being built upon. Therefore, you should download and use the version of
|
|
<application>systemd</application> your computer currently uses. The BLFS
|
|
team has no experience updating (or reverting to an older version) the
|
|
<application>Udev</application> programs <quote>on the fly.</quote> To
|
|
discover the version of <application>Udev</application> your computer
|
|
currently uses, issue <command>/sbin/udevadm --version</command>.</para>
