57 and installing from within the minimal linux environment provided by 254</p>
58 the Gentoo boot CD. It is possible, however, for users to install 255
59 Gentoo Linux directly from an already-existing Linux distribution. 256</body>
60 Such users need only download the .tbz2 file, install the contents
61 on a spare partition (making sure to use the <c>p</c> flag when
62 untarring the tarball!), chroot, and install in the usual fashion.</p>

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
280<e>meta-distribution</e>.

284Gentoo is very actively developed. Not only the <e>ebuilds</e> themselves (the
285package format Gentoo uses) but the entire distribution uses a rapid pace

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

81 <title>I have a Sony Super-Slim VAIO laptop, and the Gentoo Linux CD is having problems
82 finding my PCMCIA ATAPI CD-ROM.</title>
83 <body>
84 <p>Make sure the second IDE port is set to CDROM (it unsets itself if the device isn't
85 attached on boot) then do the following at the isolinux <c>boot:</c> prompt:</p>
86<pre>
87boot: <i>rescue ide2=0x180,0x386</i>
88</pre>
89<p>If you are using a 1.0_rc5 or earlier boot CD, apart from thinking about downloading the latest iso,
90type <c>gentoo</c> instead of <c>rescue</c>, above.</p>

95 <title>I'm finding things to be really unstable and I'm using "-O9 -ffast-math
96 -fomit-frame-pointer" optimizations. What gives?</title>
97 <body>
98 <p>When you use any optimizations beyond <c>-O3</c>, you're really taking the risk of
99 having broken packages.
100 Very aggressive optimizations sometimes cause the compiler to streamline the assembly code
101 to the point where it doesn't quite do the same thing anymore. <e>Loc-Dog</e> (on IRC)
102 uses <c>-O3 -mcpu=i686 -march=i686 -fforce-addr -fomit-frame-pointer -funroll-loops
103 -frerun-cse-after-loop -frerun-loop-opt -malign-functions=4</c>, which is about
104 as much as I'd want to push global optimization settings. Beyond this, it's best to use
105 ultra-high optimizations only with specific packages where you really need that extra 2%,
106 (eg graphics and various multimedia programs), and where you can easily test the package
107 to ensure that it hasn't been optimized into oblivion.</p>
108 <p>Please try first to compile with CFLAGS <c>-march= -O2</c> before reporting a bug</p>

140 <title>How do I enable devfs?</title>
141 <body>
142 <p>
143 If you're using 1.0_rc5 or greater, you don't need to do anything special to get
144 devfs working; it's already active (you did make sure that devfs was built into the
145 kernel, didn't you?).
146 However, if you are using a version of Gentoo Linux <e>prior</e> to version 1.0_rc5, add
147 <c>devfs=mount</c> to your <c>GRUB</c> kernel boot options so that the line looks something
148 like <c>kernel /boot/boot/bzImage devfs=mount foo=bar</c> The kernel will then mount the
149 <path>/dev</path> <e>devfs</e> filesystem automatically at boot-time.

153 <section>
154 <title>How to I disable devfs?</title>
155 <body>
156 <p>Under Gentoo Linux 1.0_rc6 and later, you can disable devfs by passing the
157 <c>gentoo=nodevfs</c> to the kernel.</p>

160 <section>
161 <title>How do I get a <path>/dev/mouse </path> that
162 doesn't go away when I reboot (when using devfs)?</title>
163 <body>
164 <p>
165 If you are using 1.0_rc6 or later, then you can just use <c>ln -s</c>
166 to make the usual symbolic link from <path>/dev/mouse</path>, and
167 it will be preserved between reboots.
168 </p>
169 <p>All other users need to edit <path>/etc/devfsd.conf</path>
170 and add these lines:</p>
171<pre>
172REGISTER ^misc/psaux$ CFUNCTION GLOBAL symlink misc/psaux mouse
173UNREGISTER ^misc/psaux$ CFUNCTION GLOBAL unlink mouse
174</pre>
175 <p>If you are not using the devfs PS/2 mouse <path>/dev/misc/psaux</path> device,
176 adjust the <c>misc/psaux</c> strings above accoringly. You'll then want to
177 <c>killall -HUP devfsd</c>
178 to get devfsd to reread <path>/etc/devfsd.conf</path>.</p>

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

663Yes, you can safely delete these files. But if you are on a slow
