Obarun is based on Archlinux, but incorporates several changes, modifications, additions, in its effort to run reliably, without systemd and its intrusive byproducts. Obarun separates the init and service management from the rest of the system that should be chosen "freely" by the user/sys-admin.

At the moment Obarun is only available for x86-64 architectures, as is Arch, but its own software has no such limitations on architecture.

Systemd replacement is made by Skarnet's S6 supervision suite as init and by Obarun's own 66 service management. S6 and 66 is the heart of Obarun, it is what makes it unique and special from all other linux systems.

Obarun's packages and source reside in the streamlined [obcore], [obextra], [obcommunity], [observice], and [obmultilib] repositories. The official [core], [extra], and [community] repositories from Arch Linux are retained to fit the needs of the competent Linux user. This means you get Arch-Linux, AUR, and more, without systemd of course.

Additional Tools written in script language are available to simplify/help tasks like installing software from AUR, building packages in a safe environment, installing a particular system, creating a live version of your system, managing and modifying services, and so on.

Hopefully Obarun will give people the choice of a system which will not tolerate any incursion of systemd, and one that stays simpler, easier to manage, more stable, more transparent, more open, and closer to the philosophy of unix and Linux.
