illumos-gate

illumos-gate is the core source code for the illumos operating system, which is an open-source version of the Solaris operating system originally developed by Sun Microsystems. It provides the fundamental building blocks—like the kernel, drivers, and core services—that enable a computer to run and manage hardware, files, and applications efficiently. Think of it as the foundational "engine" that powers the system, allowing developers to build, customize, or improve the software environment. illumos-gate is maintained openly, encouraging collaboration and innovation within the community of users and developers.
