Unleashed is an operating system fork of illumos (see why), which itself is a derivative of OpenSolaris and therefore has its roots in UNIX System V Release 4.
It is intended as a modern Unix operating system for developers by developers; it comes with ZFS, DTrace, Crossbow and more.
Download & Installation
The only systems currently supported are amd64-based computers and virtual machines.
Unleashed is being maintained as a hobby, and as such we cannot guarantee releasing security or other patches. Run it in production at your own risk.
IRC & Mailing Lists
You can find us in #unleashed on Freenode.
We have two mailing lists: one for general development discussions (subscribe, archives) and one with commit notifications (subscribe, archives).
Security sensitive information can be sent to firstname.lastname@example.org. If you wish, you may encrypt your message with Jeff's PGP key.
If you want to make Unleashed better, send us a patch, an email, or join us on IRC! We don't have mandatory code review or any other convoluted processes; just show us the code.
The source code itself is split across several git repositories:
The steps to build each vary, but they are documented in each repository's top-level README.
Aside from the typical set of man pages, there is a docs directory in the main git repository.
