60 Gentoo Linux directly from an already-existing Linux distribution.

276With Gentoo you can build your entire system from source completely using your
277choice of optimizations. You have complete control over what packages are or
278aren't installed. Gentoo provides you with numerous choices so you can install
279Gentoo to your own taste. This is why Gentoo is called a

287mainline tree, documentation is updated on daily basis, portage features are
288added frequently, releases succeed each other quickly, ...

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>

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>

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.

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>

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>
172<pre>
173REGISTER ^misc/psaux$ CFUNCTION GLOBAL symlink misc/psaux mouse
174UNREGISTER ^misc/psaux$ CFUNCTION GLOBAL unlink mouse
175</pre>
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

664Yes, you can safely delete these files. But if you are on a slow
