Photon RPM OSTree: Preface

To my knowledge, this is the first online documentation that exposes the secrets of RPM-OSTree in a practical manner, with code examples at every step of the way.

While it started as a set of Wiki pages on this topic, it ended up in some sort of a mini online book, taking the reader from theoretical concepts to practical samples, from simple to complex, in a progressive way. I've tried as much as I can not to duplicate information that is already available at other sites, limiting to only how much is needed to understand the practical examples.

I wrote this mini-book from my own notes, based on my own experiments with this technology and working with my counter-part developer for the feature. It was necessary to understand how RPM-OSTree works in order to prepare test cases for its Photon implementation, even though public documentation is very sparse and sample code was almost non-existent. We've set the ambitious goal to make it work in Photon OS Technology Preview 2, which will be made available for VMWorld 2015 in San Francisco.

Many thanks to Touseef Liaqat, the main developer who wrote the Photon / RPM-OSTree integration code. Also, many thanks to the people (whom I never met) who designed this technology.

Should you have any question, comments, suggestions, corrections (well, my first language is not English), please write to me at dmoraru@vmware.com or danutm@msn.com.

I have not much Linux experience, even less kernel knowledge. (I've worked for Microsoft for over 13 years, where pronouncing "Linux" or "open source" was sure to make some people uncomfortable. Now things have changed even there.) But now I just turned two months ... of employment with WMware. It's been awesome so far!
