The info has been severly outdated. And some info is even incorrect from day one, for example even Glibc and GCC are not listed for LSB core (they provide libc.so.6, libstdc++.so.6, etc.).

<para>The LSB has four separate specifications: Core, Desktop,
|
|
Languages, and Imaging. Some parts of Core and Desktop
|
|
specifications are architecture specific. There are also two trial
|
|
specifications: Gtk3 and Graphics. LFS attempts to conform to the LSB
|
|
specifications for the IA32 (32-bit x86) or AMD64 (x86_64)
|
|
architectures discussed in the previous section.</para>
|
|
|
|
<note><para>Many people do not agree with these requirements.
|
|
The main purpose of the LSB is to ensure that proprietary software
|
|
can be installed and run on a compliant system.
|
|
Since LFS is source based, the user has complete control over what
|
|
packages are desired; you may choose not to install some packages that
|
|
are specified by the LSB.</para></note>

<para>While it is possible to create a complete system that will pass the LSB

additional packages can be found in BLFS. </para>
