Break in what way?  Adding a few extra lines?  How do you define small steps?  Steps which happen quickly, or which don't output very much?  Hopefully most people should not need to look at `install.log` at all if we do our job right, but having visual feedback of how quickly the barclamp installs are progressing should be useful every single time someone does an install.

Of course I can split this into an extra pull request if you want, although I think we have much bigger fish to fry than these quibbles ;)
