Base system
There is no official "base system" of the GNU operating system. GNU was designed to be a replacement for Unix operating systems of the 1980s and used the POSIX standards as a guide, but either definition would give a much larger "base system". The following list is instead a small set of GNU packages which seem closer to being "core" packages than being in any of the further down sections. Inclusions (such as plotutils) and exclusions (such as the C standard library) are of course debatable.

Notes
- ↑ Stable versions. Note that some distros (e.g., Gentoo) use some development versions in case the stable versions are a bit old.
- ↑ Note that because GNU Hurd is under active development, there is no stable version. The Hurd is distributed through version control systems.
- ↑ No stable version yet. Current version is alpha and is not suitable for use in production systems.
