Explanation to the /bin, /usr/bin, /sbin, /usr/sbin split.

Well back during the early days of Unix development the makers ended up having to deal with two 1.5MB hard drives (Yes….MB) as opposed to just one, as they needed more space than they had available to them. So, as the OS grew they split the directories among different physical drives and mount points, and it’s been that way ever since. Surprising right?
