HeylelOS is an open source project aimed at creating a modern unix-like operating system. It is based on the Linux kernel, and is composed of completely original userspace components.
Lots of unix-like operating systems have a long inheritance from legacy behaviours. While this isn't necessarily a problem, modern operating systems tend to provide a user experience far away from what we could be providing today.
This project was born from the frustration of not finding a single desktop environment having a complete and unclustered integration with its base components. If you think from the perspective of a beginner user: What is a package? Why should I upgrade those so often? Why do my X11 server config keeps failing again and again? Where is my GPU driver? Any end-user shouldn't even have to worry about that kind of things. It should just work out of the box, no strings attached.
The operating system is based upon a rolling-release model. The user shouldn't have to install, maintain, update and upgrade his/her packages. The system automatically installs and replaces itself through time. May it be binaries, libraries kernels and drivers. The user should only install personal packages on his/her home prefix directories. And if you don't like the given system, feel free to fork the distribution!
"Heylel" is a rough transliteration of the original hebrew word translated in the Latin Bible to "Lucifer" (Book of Isaiah 14.12.). It designated the "morning star, Venus" but could also mean "light-bringing". It's an echo to the UNIX "mythology" around daemons, but also a reference to Prometheus, the "light-bringing" Titan.
