Computer is new 13" retina MBP. 2.9GHz i5, 16GB RAM, 256GB SSD.
I have been working on some dotfile setup scripts for my new computer and thought I had them dialed in, but did not really work how I wanted. So I restarted, hit CMD+R and chose "reinstall Yosemite" because I wanted to try again.
It just occurred to me I was not sure if doing that, repeatedly if needed, can cause any issues with the hard drive or anything?
