Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Previously there were only two association types available, namely depends on and hosted on."

Any command-line input or output is written as follows:

sysctl -w kernel.shmmax=4294967295

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Clicking the Next button moves you to the next screen".
