Illumos
Illumos (stylized as "illumos") is a partly free and open-source Unix operating system. It has been developed since 2010 and is based on OpenSolaris, after the discontinuation of that product by Oracle. It comprises a kernel, device drivers, system libraries, and utility software for system administration. Its core has become the base for many different open-sourced Illumos distributions, in a way similar to how the Linux kernel is used in different Linux distributions.
The maintainers write illumos in lowercase, since some computer fonts do not clearly distinguish a lowercase L from an uppercase i: Il (see homoglyph). The project name is a combination of words illuminare from the Latin for to light, and OS for Operating System.
Illumos was announced via webinar on 3 August 2010, as a community effort of a group of core Solaris engineers to create a truly open source Solaris, by swapping closed source bits of OpenSolaris with open implementations. OpenSolaris itself is based on System V Release 4 (SVR4) and the Berkeley Software Distribution (BSD).
The original plan explicitly stated that Illumos would not be a distribution or a fork. However, after Oracle announced the discontinuation of OpenSolaris, plans were made to fork the final version of the Solaris ON kernel, allowing Illumos to evolve into a kernel of its own. As of 2010[update], efforts focused on libc, the NFS lock manager, the crypto module, and many device drivers, to create a Solaris-like OS with no closed, proprietary code. As of 2012[update], development emphasis includes transitioning from the historical compiler, Studio, to GCC. The "userland" software is now built with GNU make, and contains many GNU utilities such as GNU tar. At the time,[clarification needed] Illumos had been lightly led by founder Garrett D'Amore and other community members/developers such as Bryan Cantrill and Adam Leventhal, via a Developers' Council.
As of 2019 its primary development project, illumos-gate, derives from OS/Net (aka ON), which is a Solaris kernel with the bulk of the drivers, core libraries, and basic utilities, similar to what is delivered by a BSD "src" tree. It was originally dependent on OpenSolaris OS/Net, but a fork was made after Oracle silently decided to close the development of Solaris and unofficially killed the OpenSolaris project.
