SlapOS system image is the fastest way to create a SlapOS node either on a real dedicated PC or using a virtual machine. It can be downloaded from SuSE Studio at the following URL: http://susestudio.com/a/MQm3Ka/slapos-image
Once the image has been download, you can create a new SlapOS node by following the tutorial "How to Create SlapOS Node from Image".
SlapOS Node package is the best way to run SlapOS on your laptop or desktop PC and contribute to SlapOS community cloud. Binary packages for GNU/Linux distributions are available, Windows, MacOS and BSD will be available soon.
There is no binary package for SlapOS Master because... there is no need for such a package. SlapOS Master can be boostrapped from slapgrid daemon, by following the SlapOS Master instantiation how-to.
Thanks to binary caching provided (in the future) by SlapOS, the bootstrap process (will) only take a few seconds.
SlapOS officially supported recipes are contained in a python distribution named "slapos.cookbook", published on PyPI. SlapOS can also use non-official recipes, likely to be also on the PyPI index.
SlapOS source code is located on the Git repositories of VIFIB SARL, the original creator of SlapOS, with fully synced mirrors on Gitorious, GitHub and OW2.
SlapOS has two official repositories : "SlapOS.core", which contains the main codebase for SlapOS (including Slapgrid, SlapOS Master, libslap, etc), and "SlapOS", containing all the profiles and the recipes you can install with SlapOS (including generic recipes, templates, application profiles, etc).
