> you mean like a package manager? what's wrong with apt, brew etc
Yes, like a universal package manager, but only for quick and dirty dev environment setup. The problem with apt, brew etc is that brew is for Mac only, and APT is for debian-like distros only.
the script at https://get.docker.com/ is exactly what I was thinking of building. Thanks for the pointer. Now I can't think of anything for which Xin-like thing would be useful apart from Vagrant installation.
