[LAD] ( Custom Arch Linux or Custom Ubuntu Studio ) for ( Proffesional Audio & Game Audio Development )

Hi !!! I've been some years with linux but I'm not an expert. I only use Ubuntu, Ubuntu Studio and CentOS for 10 years. Now, I want to be a proffesional audio developer, and is VERY FRUSTATING to my return to windows. So, [ 1 ] I want build a custom live linux system in USB or CD...for audio production for audio designers and enginners and for evangelist linux as I can. [ 2 ] I want, also, some way to build audio game engine tools, but Unreal4 or Unity 3D isn't work on linux at now, some suggest for my frustation ??? I look up for a custom bootstrap on github for that but I dont find some script done yet. I want learn to have all control on my hands, and my best are Open Source. Any help and/or Collaboration ??? So, Where I should become ? Thanks very much, Juan
