58 and installing from within the minimal linux environment provided by
59 the Gentoo boot CD. It is possible, however, for users to install
60 Gentoo Linux directly from an already-existing Linux distribution.
61 Such users need only download the .tbz2 file, install the contents
62 on a spare partition (making sure to use the <c>p</c> flag when
63 untarring the tarball!), chroot, and install in the usual fashion.</p>

284With Gentoo you can build your entire system from source, using your choice of
285optimizations. You have complete control over what packages are or aren't
286installed. Gentoo provides you with numerous choices, so you can install Gentoo
287to your own preferences, which is why Gentoo is called a <e>meta-distribution</e>.
291Gentoo is actively developed. The entire distribution uses a rapid pace
292development style: patches to the packages are quickly integrated in the
293mainline tree, documentation is updated on daily basis, Portage features are
294added frequently, and official releases occur twice per year.

82 <title>I have a Sony Super-Slim VAIO laptop, and the Gentoo Linux CD is having problems
83 finding my PCMCIA ATAPI CD-ROM.</title>
84 <body>
85 <p>Make sure the second IDE port is set to CDROM (it unsets itself if the device isn't
86 attached on boot) then do the following at the isolinux <c>boot:</c> prompt:</p>
88boot: <i>rescue ide2=0x180,0x386</i>
90<p>If you are using a 1.0_rc5 or earlier boot CD, apart from thinking about downloading the latest iso,
91type <c>gentoo</c> instead of <c>rescue</c>, above.</p>
95 <section>
96 <title>I'm finding things to be really unstable and I'm using "-O9 -ffast-math
97 -fomit-frame-pointer" optimizations. What gives?</title>
98 <body>
99 <p>When you use any optimizations beyond <c>-O3</c>, you're really taking the risk of
100 having broken packages.
101 Very aggressive optimizations sometimes cause the compiler to streamline the assembly code
102 to the point where it doesn't quite do the same thing anymore. <e>Loc-Dog</e> (on IRC)
103 uses <c>-O3 -mcpu=i686 -march=i686 -fforce-addr -fomit-frame-pointer -funroll-loops
104 -frerun-cse-after-loop -frerun-loop-opt -malign-functions=4</c>, which is about
105 as much as I'd want to push global optimization settings. Beyond this, it's best to use
106 ultra-high optimizations only with specific packages where you really need that extra 2%,
107 (eg graphics and various multimedia programs), and where you can easily test the package
108 to ensure that it hasn't been optimized into oblivion.</p>
109 <p>Please try first to compile with CFLAGS <c>-march= -O2</c> before reporting a bug</p>

119 <title>How can i change the root (or indeed any other user's) password?</title>
120 <body><p>You can use <c>passwd</c> to change the password for the user you are logged into.
121 for extra options and setting, please see <c>man passwd</c> once you've completed the install.

128 <p>The command <c>adduser gentoo</c> will add a user called gentoo. The next step is to give
129 this user a password and <c>passwd</c> will do exactly that.</p>

133 <title>Why can't a user su to root?</title>

135 <e>wheel</e> group. To add a <i>username</i> to the <e>wheel</e> group, issue the following
136 command as root:</p>
137 <pre># <i>usermod -G users,wheel username</i></pre>

141 <title>How do I enable devfs?</title>
142 <body>
143 <p>
144 If you're using 1.0_rc5 or greater, you don't need to do anything special to get
145 devfs working; it's already active (you did make sure that devfs was built into the
146 kernel, didn't you?).
147 However, if you are using a version of Gentoo Linux <e>prior</e> to version 1.0_rc5, add
148 <c>devfs=mount</c> to your <c>GRUB</c> kernel boot options so that the line looks something
149 like <c>kernel /boot/boot/bzImage devfs=mount foo=bar</c> The kernel will then mount the
150 <path>/dev</path> <e>devfs</e> filesystem automatically at boot-time.
151 </p>
152 </body>
153 </section>
154 <section>
155 <title>How to I disable devfs?</title>
156 <body>
157 <p>Under Gentoo Linux 1.0_rc6 and later, you can disable devfs by passing the
158 <c>gentoo=nodevfs</c> to the kernel.</p>
159 </body>
160 </section>
161 <section>
162 <title>How do I get a <path>/dev/mouse </path> that
163 doesn't go away when I reboot (when using devfs)?</title>
164 <body>
165 <p>
166 If you are using 1.0_rc6 or later, then you can just use <c>ln -s</c>
167 to make the usual symbolic link from <path>/dev/mouse</path>, and
168 it will be preserved between reboots.
169 </p>
170 <p>All other users need to edit <path>/etc/devfsd.conf</path>
171 and add these lines:</p>
173REGISTER ^misc/psaux$ CFUNCTION GLOBAL symlink misc/psaux mouse
174UNREGISTER ^misc/psaux$ CFUNCTION GLOBAL unlink mouse
176 <p>If you are not using the devfs PS/2 mouse <path>/dev/misc/psaux</path> device,
177 adjust the <c>misc/psaux</c> strings above accoringly. You'll then want to
178 <c>killall -HUP devfsd</c>
179 to get devfsd to reread <path>/etc/devfsd.conf</path>.</p>

183 <title>Grub can't find stage x.y?</title>
184 <body><p>
185 During installation the grub boot files are copied
186 to <path>/boot/grub</path> (<path>/boot/boot/grub</path> in Gentoo Linux 1.0_rc5 and
187 earlier.) Grub automatically looks in the <path>/boot/grub</path> directory on the boot
188 partition. (We strongly recommend having a separate no-auto boot partition mounted at
189 <path>/boot</path>, since that way it is much more difficult to clobber your kernel and boot
190 info by accident.) The above error generally arises from (a) not using a separate boot
191 partition, (b) forgetting to mount the boot partition at <path>/boot</path> before either
192 unpacking the build snapshot or running
193 <c>emerge --usepkg system</c>, or (c) forgetting the
194 <c>notail</c> option when mounting a ReiserFS <path>/boot</path> partition.
195 You can get more information on grub, including how to
196 debug grub from the grub prompt, by reading the

622 <title>Why, when I hit reply to a post on a Gentoo mailing list, does my answer
623 only go to the original poster and not the entire list?</title>
624 <body>
625 <p>The mailing list administrators have decided to go with minimal munging
626 (altering of mail headers), which means that they have decided against
627 altering headers to have replies go to the mailing list. There are various
628 reasons for this. For example, if a subscriber has a full mailbox, the
629 entire list receives notice of this every time that something is posted.
631 Most GUI based mailers have a "reply to all" function. This will ensure that
632 your reply goes to the mailing list as well as the original poster. Most
633 users of text based emailers already know the methods to use, but if you
634 don't, in Pine, there is a "reply to group" option. Setting Mutt to reply to
635 the list is covered in the unofficial documentation at
636 <uri link="http://forums.gentoo.org/viewtopic.php?t=1085">forums.gentoo.org</uri>.
638 Some list members do not like this method, but it was very heavily
639 discussed when it went into effect, with arguments on both sides.
640 Eventually the list administrators decided to keep it this way. Discussing
641 it on the mailing list will sometimes bring a polite explanation and other
642 times a rather brusque comment to check the archives. Although the
643 administrators regret the inconvenience that it may cause some users, it is
644 felt that at present it is preferable to the alternative for several
645 reasons, many of these covered
646 <uri link="http://www.unicom.com/pw/reply-to-harmful.html">here</uri>.
648 (There are other eloquent arguments in favor of munging, and yes, the list
649 administrators have seen them.) </p>
