Lack of OS abstraction leads to code duplication.

I'm doing directory synchronization using rsync and other tools. This is a separate role, but I guess it should work for any Linux system (well any that can have rsync installed).

So I assumed that it could be put inside linux package, but I have to ensure that rsync is installed on remote server --- which requires me to use packaging role specific for the distribution.

I thing that it would be very valuable to extract some common packaging functionalities, so I could say: "Install rsync using proper way for the current OS".

Any ideas?
