ZealOS

The Zeal Operating System is a modernized, professional fork of the 64-bit Temple Operating System. Guiding principles of development include transparency, full user control, and adherence to public-domain/open-source implementations.

ZealOS strives to be simple, documented, and require as little of a knowledge gap as possible. One person should be able to comprehend the entire system in at least a semi-detailed way within a few days of study. Simplify, don't complicate; make accessible, don't obfuscate.

The CIA encourages code obfuscation. They make it more complicated than necessary.
—Terry A. Davis

Getting started

Prerequisites

For running in a VM: Intel VT-x/AMD-V acceleration enabled in your BIOS settings. (Required to virtualize any 64-bit operating system properly.)
Working knowledge of the C programming language.

To create a Distro ISO, run build_iso.sh in the build/ directory. After creating an ISO, see the Wiki for guides on installing in VirtualBox, VMWare, and bare-metal.

Contributing

There are two ways to contribute. The first way involves everything happening inside the OS, as intended by Terry. After you've built the latest ISO, installed to a VM, made your changes, and powered off the VM, you can run the sync_repo.sh script to merge your changes to the repo.

Alternatively, you can edit repo files using an external editor, outside of the OS.

Afterwards, you can make a pull request on the master branch.

Background

In around November of 2019, VoidNV forked ZenithOS from TempleOS to continue Terry's work in a direction that would make it a viable operating system while still keeping the innovative and divine-intellect ideas and design strategies intact. At first, development occurred exclusively inside a VM and ISOs were occasionally generated as official releases, but this was scrapped and restarted from scratch. Releases of the "old" ZenithOS are currently archived on the mega.nz website. The repository was removed in August of 2020, and reuploaded to ZenithOS. The latest archived front page, master.zip, and related links can be found on archive.org.

In July of 2021, ZealOS was forked from ZenithOS.
