v. LFS and Standards
The structure of LFS follows Linux standards as closely as possible. The primary standards are:
-
Linux Standard Base (LSB) Version 5.0 (2015)
The LSB has four separate specifications: Core, Desktop, Runtime 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 generic specifications. The architecture specific part of LSB does not exist for ARM64.

Note
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.
While it is possible to create a complete system that will pass the LSB certification tests "from scratch", this can't be done without many additional packages that are beyond the scope of the LFS book. Installation instructions for these additional packages can be found in BLFS.
