25 <p>
26 Working as root on a Unix/Linux system is <e>dangerous</e> and should be avoided
27 as much as possible. Therefore it is <e>strongly</e> recommended to add a user
28 for day-to-day use.
29 </p>
30
31 <p>
32 The groups the user is member of define what activities the user can perform.
33 The following table lists a number of important groups you might wish to use:
34 </p>

36 <table>
37 <tr>
38 <th>Group</th>
39 <th>Description</th>
40 </tr>
41 <tr>
42 <ti>audio</ti>
43 <ti>be able to access the audio devices</ti>
44 </tr>
45 <tr>
46 <ti>cdrom</ti>
47 <ti>be able to directly access optical devices</ti>
48 </tr>
49 <tr>

51 <ti>be able to directly access floppy devices</ti>
52 </tr>
53 <tr>
54 <ti>games</ti>
55 <ti>be able to play games</ti>
56 </tr>
57 <tr>
58 <ti>portage</ti>
59 <ti>be able to use <c>emerge --pretend</c> as a normal user</ti>
60 </tr>
61 <tr>
62 <ti>usb</ti>
63 <ti>be able to access USB devices</ti>
64 </tr>
65 <tr>
66 <ti>video</ti>
67 <ti>
68 be able to access video capturing hardware and doing hardware
69 acceleration
70 </ti>
71 </tr>
72 <tr>
73 <ti>wheel</ti>
74 <ti>be able to use <c>su</c></ti>
75 </tr>
76 </table>
77
78 <p>
79 For instance, to create a user called <c>john</c> who is member of the
80 <c>wheel</c>, <c>users</c> and <c>audio</c> groups, log in as root first
81 (only root can create users) and run <c>useradd</c>:
82 </p>
83
84 <pre caption="Adding a user for day-to-day use">
85 Login: <i>root</i>
86 Password: <comment>(Your root password)</comment>
87
88 # <i>useradd -m -G users,wheel,audio -s /bin/bash john</i>
89 # <i>passwd john</i>
90 Password: <comment>(Enter the password for john)</comment>
91 Re-enter password: <comment>(Re-enter the password to verify)</comment>
92 </pre>
93
94 <p>
95 If a user ever needs to perform some task as root, they can use <c>su -</c>
96 to temporarily receive root privileges. Another way is to use the <c>sudo</c>
97 package which is, if correctly configured, very secure.

110 Now that you've finished installing Gentoo and rebooted, if everything has gone
111 well, you can remove the downloaded stage3 tarball and Portage snapshot from
112 your hard disk. Remember that they were downloaded to your <path>/</path>
113 directory.
