13     <title>Setting a root Password</title>
14 swift 1.1 <body>
15    
16     <p>
17 swift 1.4 Before you forget, set the root password by typing:
18     </p>
19    
20     <pre caption="Setting the root password">
21     # <i>passwd</i>
22     </pre>
23    
24 swift 1.11 <p>
25     If you want root to be able to log on through the serial console, add
26 swift 1.22 <c>tts/0</c> to <path>/etc/securetty</path>:
27 swift 1.11 </p>
28    
29 swift 1.22 <pre caption="Adding tts/0 to /etc/securetty">
30     # <i>echo "tts/0" &gt;&gt; /etc/securetty</i>

36     <title>Adding a User for Daily Use</title>
37     <body>
38    
39     <p>
40     Working as root on a Unix/Linux system is <e>dangerous</e> and should be avoided
41 swift 1.10 as much as possible. Therefore it is <e>strongly</e> recommended to add a user
42 swift 1.4 for day-to-day use.
43     </p>
44    
45     <p>
46     For instance, to create a user called <c>john</c> who is member of the
47     <c>wheel</c> group (be able to change to root using <c>su</c>), <c>users</c>
48     group (default for all users) and <c>audio</c> group (be able to use audio
49     devices):
50     </p>
51    
52     <pre caption="Adding a user for day-to-day use">
53 swift 1.28 # <i>useradd john -m -G users,wheel,audio,tty -s /bin/bash</i>
54 swift 1.4 # <i>passwd john</i>
55     Password: <comment>(Enter the password for john)</comment>
56     Re-enter password: <comment>(Re-enter the password to verify)</comment>
57     </pre>
58    
59     <p>
60 swift 1.26 If a user ever needs to perform some task as root, they can use <c>su -</c>
61 swift 1.25 to temporarily receive root privileges. Another way is to use the <c>sudo</c>
62 swift 1.4 package which is, if correctly configured, very secure.

73    
74     <p>
75 swift 1.18 Congratulations! Your Gentoo system is now ready. Exit the chrooted environment
76 swift 1.23 and unmount all mounted partitions. Then type in that
77 swift 1.15 one magical command you have been waiting for: <c>reboot</c>.
78 swift 1.4 </p>
79    
80     <pre caption="Rebooting the system">
81     # <i>exit</i>
82     # <i>cd /</i>
83     # <i>umount /mnt/gentoo/boot /mnt/gentoo/proc /mnt/gentoo</i>
84     # <i>reboot</i>
85     </pre>
86    
87     <p>
88 swift 1.6 Of course, don't forget to remove the bootable CD, otherwise the CD will be
89 swift 1.4 booted again instead of your new Gentoo system.
90     </p>
91    
92     <p>
93 swift 1.24 OldWorld <b>PPC</b> users will boot in MacOS since their bootloader
94 swift 1.4 isn't installed yet. Those users should read <uri
95 swift 1.24 link="#doc_chap2_sect2">Optional: Configuring BootX</uri>. <b>MIPS</b> users
96     will have to do some more tweaking in their MIPS PROM to get Gentoo to work.
97     Those users should read <uri link="#doc_chap2_sect3">Optional: Getting
98     Gentoo/MIPS to Work</uri>.
99 swift 1.19 </p>
100    
101     <p>
102     GRP users can continue with <uri link="#doc_chap2_sect4">Optional:
103     Install GRP Packages</uri>, all the rest can finish up with <uri
104 swift 1.4 link="?part=1&amp;chap=12">Where to go from here?</uri>.

110 swift 1.2 <title>Optional: Configuring BootX</title>
111     <body>
112    
113 swift 1.4 <impo>
114 swift 1.24 This subsection is <e>only</e> for <b>PPC</b> users who want to use BootX as
115 swift 1.3 bootloader. All other readers should skip this subsection.
116 swift 1.4 </impo>
117 swift 1.2
118     <p>
119     Now your machine is booted in MacOS, open the BootX control panel.
120     Select <c>Options</c>, and uncheck <c>Used specified RAM disk</c>. When you
121     return to the BootX main screen, you will now find an option to specify your
122     machine's root disk and partition. Fill these in with the appropriate
123     values.
124     </p>
125    
126     <p>
127     BootX can be configured to start Linux upon boot. If you do this, you will
128     first see your machine boot into MacOS then, during startup, BootX will
129     load and start Linux. See the <uri
130     link="http://penguinppc.org/projects/bootx/">BootX home page</uri> for more
131     information.
132     </p>

134 swift 1.4 <p>
135     If you are a GRP users you can continue with <uri
136 swift 1.19 link="#doc_chap2_sect4">Optional: Install GRP Packages</uri>, otherwise go to

147     This subsection is <e>only</e> for <b>MIPS</b> users! All other readers should

151 swift 1.11 <p>
152     When you are rebooted, go to the <e>System Maintenance Menu</e> and select
153     <e>Enter Command Monitor</e> (<c>5</c>). If you want to test your new Gentoo
154     installation, you can just run <c>boot -f &lt;kernel name&gt;</c>. To have your
155     system permanently boot into the Gentoo installation, you need to set some
156     variables in the MIPS PROM:
157     </p>
158    
159     <pre caption="Configuring the PROM to Boot Gentoo">
160     1) Start System
161     2) Install System Software
162     3) Run Diagnostics
163     4) Recover System
164     5) Enter Command Monitor
165    
166     Option? <i>5</i>
167     Command Monitor. Type "exit" to return to the menu.

190     </pre>
191    
192     <p>
193     Now you're ready to enjoy Gentoo!
194     </p>

198     <subsection>
199 swift 1.19 <title>Optional: Install GRP Packages</title>
200 swift 1.1 <body>
201    
202 swift 1.4 <impo>
203     This part is for GRP users only. Other users should skip this part and continue
204     with <uri link="?part=1&amp;chap=12">Where to go from here?</uri>.
205     </impo>
206    
207     <p>
208     Now that your system is booted, log on as the user you created (for instance,
209     <c>john</c>) and use <c>su -</c> to gain root privileges:
210     </p>
211    
212     <pre caption="Gaining root privileges">
213     $ <i>su -</i>
214     Password: <comment>(Enter your root password)</comment>
215     </pre>
216    
217     <p>
218 swift 1.20 Now we need to change the Portage configuration to look for the prebuilt
219 swift 1.21 binaries from the second CD (Gentoo Packages CD). First mount this CD:
220 swift 1.4 </p>
221    
222 swift 1.21 <pre caption="Mount the Packages CD">
223     <comment>(Put the Gentoo Packages CD in the CD tray)</comment>
224 swift 1.4 # <i>mount /mnt/cdrom</i>
225     </pre>
226    
227 swift 1.1 <p>
228 swift 1.20 Now configure Portage to use <path>/mnt/cdrom</path> for its prebuilt packages:
229 swift 1.4 </p>
230    
231 swift 1.20 <pre caption="Configuring Portage to use /mnt/cdrom">
232     # <i>ls /mnt/cdrom</i>
233    
234     <comment>(If there is a /mnt/cdrom/packages directory:)</comment>
235     # <i>export PKGDIR="/mnt/cdrom/packages"</i>
236    
237     <comment>(Otherwise:)</comment>
238     # <i>export PKGDIR="/mnt/cdrom"</i>
239 swift 1.4 </pre>
240    
241     <p>
242 swift 1.21 Now install the packages you want. The Packages CD contains several prebuilt
243     binaries, for instance KDE:
244 swift 1.4 </p>
245    
246     <pre caption="Installing KDE">
247 swift 1.19 # <i>USE="bindist" emerge --usepkg kde</i>
248 swift 1.4 </pre>
249    
250     <p>
251 swift 1.19 The <c>USE="bindist"</c> is needed when you install XFree (either directly or as
252     a dependency). It prevents the downloading of Microsoft's core fonts (which we
253     cannot distribute on our LiveCDs).
254     </p>
255    
256     <p>
257 swift 1.4 Be sure to install the binaries now. When you do an <c>emerge sync</c> to update
258     Portage (as you will learn later), the prebuilt binaries might not match against
259     the ebuilds in your updated Portage. You can try to circumvent this by using
260 swift 1.9 <c>emerge --usepkgonly</c> instead of <c>emerge --usepkg</c>.
261 swift 1.4 </p>
262    
263     <p>
264     Congratulations, your system is now fully equiped! Continue with <uri
265     link="?part=1&amp;chap=12">Where to go from here?</uri> to learn more about
266     Gentoo.
