Provide a standalone POSIX-shell script used to identify a Linux distribution and version
distro-id output is modeled after lsb_release output to be easily parseable.
This has very few dependencies, and is intended to be functional in minimal
Target applications include out-of-distro applications that need to expose OS

cannot test for a given interface and must instead rely on heuristics. If
it is feasible to test for an interface, it is recommended to do so instead
of making assumptions about a system.
