 Among their proposed standards are the Linux Standard Base, which defines a common ABI and packaging system for Linux, and the Filesystem Hierarchy Standard which recommends a standard filenaming chart, notably the basic directory names found on the root of the tree of any Linux filesystem.Those standards, however, see limited use, even among the distributions developed by members of the organization.The diversity of Linux distributions means that not all software runs on all distributions, depending on what libraries and other system attributes are required.
