14 Before you forget, set the root password by typing:

24 <title>Adding a User for Daily Use</title>
25 <body>
26
27 <p>
28 Working as root on a Unix/Linux system is <e>dangerous</e> and should be avoided
29 as much as possible. Therefor it is <e>strongly</e> recommended to add a user
30 for day-to-day use.
31 </p>
32
33 <p>
34 For instance, to create a user called <c>john</c> who is member of the
35 <c>wheel</c> group (be able to change to root using <c>su</c>), <c>users</c>
36 group (default for all users) and <c>audio</c> group (be able to use audio
37 devices):
38 </p>
39
40 <pre caption="Adding a user for day-to-day use">
41 # <i>useradd john -m -G users,wheel,audio -s /bin/bash</i>
42 # <i>passwd john</i>
43 Password: <comment>(Enter the password for john)</comment>
44 Re-enter password: <comment>(Re-enter the password to verify)</comment>
45 </pre>
46
47 <p>
48 If this user ever needs to perform some task as root, he can use <c>su -</c> to
49 temporarily receive root privileges. Another way is to use the <c>sudo</c>
50 package which is, if correctly configured, very secure.

62 <p>
63 Congratulations! Your Gentoo system is now ready. Run <c>etc-update</c> to
64 update the configuration files (if needed), exit the chrooted environment and
65 unmount all mounted partitions. Then type in that one magical command you have
66 been waiting for: <c>reboot</c>.
67 </p>
68
69 <pre caption="Rebooting the system">
70 # <i>etc-update</i>
71 # <i>exit</i>
72 # <i>cd /</i>
73 # <i>umount /mnt/gentoo/boot /mnt/gentoo/proc /mnt/gentoo</i>
74 # <i>reboot</i>
75 </pre>
76
77 <p>
78 Of course, don't forget to remove the bootable CD, otherwise the CD will be
79 booted again instead of your new Gentoo system.
80 </p>
81
82 <p>
83 OldWorld PPC users will boot in MacOS since their bootloader
84 isn't installed yet. Those users should read <uri
85 link="#doc_chap2_sect2">Optional: Configuring BootX</uri>. GRP users can
86 continue with <uri link="#doc_chap2_sect3">Optional: Install Extra
87 Packages</uri>, all the rest can finish up with <uri
88 link="?part=1&amp;chap=12">Where to go from here?</uri>.

93 <subsection>
94 <title>Optional: Configuring BootX</title>
95 <body>
96
97 <impo>
98 This subsection is <e>only</e> for PPC-users who want to use BootX as
99 bootloader. All other readers should skip this subsection.
100 </impo>
101
102 <p>
103 Now your machine is booted in MacOS, open the BootX control panel.
104 Select <c>Options</c>, and uncheck <c>Used specified RAM disk</c>. When you
105 return to the BootX main screen, you will now find an option to specify your
106 machine's root disk and partition. Fill these in with the appropriate
107 values.
108 </p>
109
110 <p>
111 BootX can be configured to start Linux upon boot. If you do this, you will
112 first see your machine boot into MacOS then, during startup, BootX will
113 load and start Linux. See the <uri
114 link="http://penguinppc.org/projects/bootx/">BootX home page</uri> for more
115 information.
116 </p>
117
118 <p>
119 If you are a GRP users you can continue with <uri
120 link="#doc_chap2_sect3">Optional: Install Extra Packages</uri>, otherwise go to
121 <uri link="?part=1&amp;chap=12">Where to go from here?</uri>.
122 </p>
123
124 </body>
125 </subsection>
126 <subsection>
127 <title>Optional: Install Extra Packages</title>
128 <body>
129
130 <impo>
131 This part is for GRP users only. Other users should skip this part and continue
132 with <uri link="?part=1&amp;chap=12">Where to go from here?</uri>.
133 </impo>
134
135 <p>
136 Now that your system is booted, log on as the user you created (for instance,
137 <c>john</c>) and use <c>su -</c> to gain root privileges:
138 </p>
139
140 <pre caption="Gaining root privileges">
141 $ <i>su -</i>
142 Password: <comment>(Enter your root password)</comment>
143 </pre>
144
145 <p>
146 Now we need to copy over the prebuild binaries from the second CD (CD-2) if you
147 have it. First mount this CD:
148 </p>
149
150 <pre caption="Mount the CD-2">
151 <comment>(Put CD-2 in the CD tray)</comment>
152 # <i>mount /mnt/cdrom</i>
153 </pre>
154
155 <p>
156 Now copy over all prebuild binaries from the CD to
157 <path>/usr/portage/packages</path>. Make sure you use the same copy-command
158 (including the trailing <path>/</path>)!
159 </p>
160
161 <pre caption="Copy over prebuild binaries">
162 # <i>cp -a /mnt/cdrom/* /usr/portage/packages/</i>
163 </pre>
164
165 <p>
166 Now install the packages you want. CD-2 contains several prebuild binaries, for
167 instance KDE:
168 </p>
169
170 <pre caption="Installing KDE">
171 # <i>emerge -k kde</i>
172 </pre>
173
174 <p>
175 Be sure to install the binaries now. When you do an <c>emerge sync</c> to update
176 Portage (as you will learn later), the prebuilt binaries might not match against
177 the ebuilds in your updated Portage. You can try to circumvent this by using
178 <c>emerge -K</c> instead of <c>emerge -k</c>.
179 </p>
180
181 <p>
182 Congratulations, your system is now fully equiped! Continue with <uri
183 link="?part=1&amp;chap=12">Where to go from here?</uri> to learn more about
184 Gentoo.
