31 |
|
---|
32 | <para>In 2012, the <application>Udev</application> code distribution was
|
---|
33 | merged with <application>systemd</application>.
|
---|
34 | <application>Systemd</application> is a set of programs that replace the
|
---|
35 | <application>SysVInit</application> package used by LFS and is much more
|
---|
36 | complex. It is not compatible with the LFS bootscripts and has many
|
---|
37 | problems and few advantages for most LFS users.</para>
|
---|
38 |
|
---|
39 | <para>The procedures below extract libraries and programs from the systemd
|
---|
40 | sources that could not be built in LFS due to library dependency
|
---|
41 | issues.</para>
|
---|
42 |
|
---|
43 | <para>Unlike any other package in the BLFS book, there is no set version
|
---|
44 | of <application>systemd</application> specified to download. Several version
|
---|
45 | updates to LFS and BLFS means there are probably many different
|
---|
46 | versions of <application>Udev</application> on the platforms that BLFS is
|
---|
47 | being built upon. Therefore, you should download and use the version of
|
---|
48 | <application>systemd</application> your computer currently uses. The BLFS
|
---|
49 | team has no experience updating (or reverting to an older version) the
|
---|
50 | <application>Udev</application> programs <quote>on the fly.</quote> To
|
---|
51 | discover the version of <application>Udev</application> your computer
|
---|
52 | currently uses, issue <command>/sbin/udevadm --version</command>.</para>
