Illumos (stylized as illumos) is a partly free and open-source Unix operating system. It is based on OpenSolaris, which was based on System V Release 4 (SVR4) and the Berkeley Software Distribution (BSD). Illumos comprises a kernel, device drivers, system libraries, and utility software for system administration. This core is now the base for many different open-sourced illumos distributions, in a similar way in which 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 Latin for to light and OS for Operating System. More information...
