The goal of Obarun is to provide an alternative for people looking for more simplicity and transparency in maintaining their systems. Obarun is not designed with beginners to Linux in mind, although after some careful reading even beginers may be able to install and enjoy Obarun.
On another note, Obarun is neither a distribution of its own, nor is it pure Archlinux, it's a Build Concept. Obarun is based on Archlinux, but incorporates several changes.
For the moment Obarun is only available for x86-64 architectures.
Systemd replacement is made by S6 init and 66 supervision suite as init and service management.
Obarun package set resides in the streamlined [obcore], [obextra], and [observice] repositories. Obviously, the official [core] and [extra] repositories from Arch Linux are used to fit the needs of the competent Linux user.
Some tools written in script language are available to simplify/help tasks like installing software from AUR, building packages on safe environment, installing a particular system, service managing and so on.
Hopefully Obarun will give people the option of choice : of a system which will not tolerate any incursion of systemd, and which stays simpler, more stable, more transparent, more open, and closer to the general philosophy of Linux.
The installer currently is able to install a base minimal system, similar to what you find in Arch without systemd, the base of the S6 init system, and the 66 service supervision system or the following window managers: JWM.
The isos available, base or Jwm run the same installer, so from each you can install any of the above mentioned 5 options. For example you can use the Jwm .iso to make a base installation or use the base .iso to make a JWM installation.
Support for running and configuring Obarun and for reporting bugs can be by participating in the Obarun Forum and/or the dedicated #Obarun xmpp channel email@example.com.
