From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Additional paths will be inserted into the search path used for executables on systems which have a compatible CPU. Those additional paths will mirror the AMD64 / x86_64 "microarchitecture levels" supported by the glibc-hwcaps mechanism: x86-64-v2, x86-64-v3, x86_64-v4. Systemd will be modified to insert the additional directories into the $PATH environment variable (affecting all programs on the system) and the equivalent internal mechanism in systemd (affecting what executables are used by services). Individual packages can provide optimized libraries via the glibc-hwcaps mechanism and optimized executables via the extended search path. This optimized code will be used if the CPU supports it. Which packages provide the optimized code and at which level will be made by individual package maintainers based on benchmark results.
