Conventions

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

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Manually building the root filesystem and configuration files using tools such as debootstrap and yum."

A block of code is set as follows:

#define _GNU_SOURCE
#include<stdlib.h>
#include<stdio.h>
#include<signal.h>
#include<sched.h>
 
staticintchildFunc(void *arg)
{
  printf("UID inside the namespace is %ld\n", (long) geteuid());
  printf("GID inside the namespace is %ld\n", (long) getegid());
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<head> 
#define _GNU_SOURCE
#include
#include
#include
#include

staticintchildFunc(void *arg)
{
  printf("UID inside the namespace is %ld\n", (long) geteuid());
  printf("GID inside the namespace is %ld\n", (long) getegid());
}

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

root@ubuntu:~# lsb_release -dc
Description:   	Ubuntu 14.04.5 LTS
Codename:      	trusty
root@ubuntu:~#

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Navigate to Networking support | Networking options | 802.1d Ethernet Bridging and select either Y to compile the bridging functionality in the kernel, or M to compile it as a module."

Note

Warnings or important notes appear in a box like this.
