That's true. But my question was actually specific to when the systems are sharing basically the same environment (kernel, library versions, etc.). A simple solution is that on each system I install qemu official package then the dependencies will all be there, then I install my custom package (which will possibly install the binaries under /usr/local) and I run the customized binary. > > For development, maybe it's easier to combine git and Ansible. I would prefer avoid using git and compiling stuff, if there is a way. :) -- Peter Xu
