Solus OS is an independent Linux distribution built from scratch, there is no parent project. Solus is a desktop-orientated, modern Linux-based operating system with a focus on user-friendliness with a custom desktop environment called “Budgie”. The Budgie Desktop tightly integrates with the GNOME stack, employing underlying technologies to offer an alternative desktop experience. Also note that Budgie can now emulate the look and feel of the GNOME 2 desktop, optionally, via a setting in the panel preferences. It uses a forked version of the PiSi package manager, maintained as “eopkg” within Solus.
