21     <title>How is Gentoo pronounced, and what does it mean?</title>
22 drobbins 1.11 <body><p>Gentoo is a species of small fast penguin, pronounced "gen-too" (The "g" in "gentoo" is a soft "g", as in "gentle".)</p></body>

26     <title>What makes Gentoo different?</title>
27     <body>
28     <p>Gentoo Linux is a fast, modern distribution with a clean and flexible
29     design -- in this respect, Gentoo may appeal to
30     <uri link="http://www.slackware.com/">Slackware</uri>,
31     <uri link="http://www.linuxfromscratch.org">Linux From Scratch</uri> or
32     <uri link="http://www.bsd.org">BSD</uri> users. Unlike most Linux
33     distros, Gentoo has a package system reminiscent of BSD's ports,
34     meaning the packages are continually updated to the lastest
35     versions.

50 drobbins 1.1 <title>What is the difference between the .iso and .tbz2 files?</title>
51     <body><p>The build <e>.tbz2</e> file is a minimal set of system files
52     that is necessary for allowing a user to bootstrap and install
53     Gentoo Linux. The build <e>.iso</e> is a complete, bootable CD image that
54     contains a system kernel, a reasonably complete set of kernel modules,
55     necessary system tools such as <c>mkfs</c> and networking support,
56     as well as the <e>.tbz2</e> minimal-system tarball. Most users will install
57     Gentoo Linux by burning the .iso file onto a CD, booting off of the CD,
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>
64     </body>
65     </section>
67     <section>
68     <title>Why do the build .iso and .tbz2 files sometimes have different -r (revision) numbers?</title>
69     <body><p>
70     The .tbz2 minimal-system tarball only needs to be revised when there have
71     been significant changes to the core Gentoo Linux system (such as baselayout
72     changes, or a new profile), and as such .tbz2 updates are relatively rare.
73     The .iso file tends to get updated whenever we discover that somebody has
74     hardware that won't boot from our .iso. Since new kernel modules and
75     patches are constantly being generated, this situation probably won't
76     stabilise anytime soon.

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>
87     <pre>
88     boot: <i>rescue ide2=0x180,0x386</i>
89     </pre>
90     <p>If you are using a 1.0_rc5 or earlier boot CD, apart from thinking about downloading the latest iso,
91     type <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 zhware 1.4 <p>Please try first to compile with CFLAGS <c>-march= -O2</c> before reporting a bug</p>

114     <title>What's the default root password after installation?</title>
115     <body><p>The default password is blank; hit enter.</p></body>
116     </section>
118     <section>
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.
122     </p></body>

124     <section>
125     <title>How do i add a normal user?</title>
126     <body><p>Everyone seems to think that i shouldn't be using <e>root</e> for everyday use,
127     how can i add another user?</p>
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>
130 zhware 1.15 <p>Insteed of <c>adduser</c> you can also use:
131     <pre># <i>useradd gentoo -m -G users,audio,wheel -s /bin/bash</i></pre>
132 zhware 1.16 This will add a user gentoo, will make possible for him to use sound-related devices (<path>/dev/sound/*</path>), will make possible for him to switch to root (using <c>su</c>) and will make <path>/bin/bash</path> his login shell.

136     <section>
137     <title>Why can't a user su to root?</title>
138     <body><p>For security reasons, users may only <c>su</c> to root if they belong to the
139     <e>wheel</e> group. To add a <i>username</i> to the <e>wheel</e> group, issue the following
140     command as root:</p>
141     <pre># <i>usermod -G users,wheel username</i></pre>

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

187     <title>Grub can't find stage x.y?</title>
188     <body><p>
189     During installation the grub boot files are copied
190     to <path>/boot/grub</path> (<path>/boot/boot/grub</path> in Gentoo Linux 1.0_rc5 and
191     earlier.) Grub automatically looks in the <path>/boot/grub</path> directory on the boot
192     partition. (We strongly recommend having a separate no-auto boot partition mounted at
193     <path>/boot</path>, since that way it is much more difficult to clobber your kernel and boot
194     info by accident.) The above error generally arises from (a) not using a separate boot
195     partition, (b) forgetting to mount the boot partition at <path>/boot</path> before either
196     unpacking the build snapshot or running
197     <c>emerge --usepkg system</c>, or (c) forgetting the
198     <c>notail</c> option when mounting a ReiserFS <path>/boot</path> partition.
199     You can get more information on grub, including how to
200     debug grub from the grub prompt, by reading the
201     <uri link="http://www-105.ibm.com/developerworks/education.nsf/linux-onlinecourse-bytitle/0F1731DC664023B7862569D0005C44AF?OpenDocument">IBM developerWorks Grub tutorial</uri>.

207     <title>My ASUS CUV4X-D won't boot and it freezes during various stages of kernel loading and hardware
208     detection. </title>
209     <body>
210     <p>Disable MPS 1.4 (multi-processor-system) in the BIOS or switch this
211     function to 1.1. By using this option you just switch the MPS version. The Multi-Processor-System
212     will still work properly. Make sure to boot Gentoo Linux with the following boot option, noapic. </p>

217     <title>If I have Gentoo 1.4_rc1 can I upgrade to 1.4_rc2, 1.4_final/_rc3 without reinstalling?</title>
218     <body>
219     In fact there is no difference between the 1.4 releases <b>after they&apos;ve installed</b>. Gentoo 1.4 and later are <c>glibc-2.3.x</c> based.
220     As such 1.4rc1 machine for example, that does <c>emerge rsync; emerge -u world</c> is <b>exactly the same</b> as a machine with 1.4rc2 installed, after it does <c>emerge rsync; emerge -u world</c>. The true differences lie in the installer.

226     <title>Package Management</title>
227     <section>
228     <title>In what format are the packages stored?</title>
229     <body><p>They exist in our portage tree as <e>ebuild</e> autobuild scripts; we are primarily
230     a ports-based distribution, meaning that we provide scripts (<c>.ebuild</c> files) and a
231     special system (Portage) so that you can build apps from sources. We generally only build
232 swift 1.22 binaries for releases and snapshots. The <uri link="/doc/en/gentoo-howto.xml">Development HOWTO
233 drobbins 1.1 </uri> covers the contents of an ebuild script in detail. For full binary ISO releases, we
234     create a full suite of binary packages in an enhanced <c>.tbz2</c> format (<c>.tar.bz2</c>
235     compatible with meta-information attached to the end of the file.)</p>

239     <section>
240     <title>Why write a new port system (Portage) instead of using BSD's version?</title>
241     <body>
242     <p>In one sentence, because Portage is much better in so many ways. One of the design
243     philosophies of the <c>.ebuild</c> syntax was to make it an analog of what you'd type to
244     install the program manually, thus making Portage very easy to learn and modify to your
245     needs. We also have OpenBSD-style "fake" installs, safe unmerging, system profiles,
246     package masking, a real dependency system, and lots of other good stuff.</p>
247     </body>
248     </section>
250     <section>
251     <title>How does this differ from Debian's apt or BSD's ports?</title>
252     <body><p>Portage features the best of apt and ports; for example, USE options, a full
253     dependency system, safe installs and uninstalls, and a true package database. Think of
254     Portage as the best of both worlds; a ports system with the sensibilities and safety of a
255     Linux package management system built-in.</p></body>

259     <title>How do I install and uninstall packages?</title>
260     <body>
261 swift 1.22 <p>The <uri link="/doc/en/portage-user.xml">Portage User Guide</uri> details how to install
262 drobbins 1.1 and uninstall packages, and update Portage.</p>
263     </body>
264     </section>
266     <section>
267     <title>How can I set a global configuration for compiling packages?</title>
268     <body><p><path>/etc/make.conf</path> should be modified to override global and
269     profile-specific default options used to compile and merge packages. The most common options
270     are as follows:</p>
271     <table>
272     <tr>
273     <th>Flag</th>
274     <th>Description</th>
275     </tr>
276     <tr>
277     <ti>CHOST</ti>
278     <ti>This sets the HOST variable for compiles, e.g. <c>i686-pc-linux-gnu</c></ti>
279     </tr>
280     <tr>
281     <ti>CFLAGS</ti>
282     <ti>The options for <c>gcc</c> when compiling programs written in C (*.c files)</ti>
283     </tr>
284     <tr>
285     <ti>CXXFLAGS</ti>
286     <ti>The options for <c>gcc</c> when compiling programs written in C++ (*.c,*.cpp etc.
287     files)</ti>
288     </tr>
289     <tr>
290     <ti>USE</ti>
291     <ti>This allows you to set what optional components you'd like compiled-in, if
292     available. For example, if you have <c>gnome</c> inside the USE string, then when
293     you compile <c>xchat</c>, it will include GNOME support. All our dependencies are
294     also USE-aware.</ti>
295     </tr>
296     <tr>
297     <ti>GENTOO_MIRRORS</ti>
298     <ti>A space separated list of URIs currently mirroring the Gentoo packages. Portage
299     will attempt download from a <c>GENTOO_MIRROR</c> first before trying the official
300     <c>SRC_URI</c>. To force Portage to skip mirrors, set this variable to "".</ti>
301     </tr>
302     </table>
303     </body>
304     </section>
306     <section>
307     <title>What happened to <path>/etc/make.defaults</path>?</title>
308     <body>
309     <p>As of Portage 1.5 onwards, <path>/etc/make.defaults</path> is antiquated;
310     if you have portage-1.5-r1 or above installed then you can safely delete it.
311     This file has been replaced by <path>/etc/make.profile/make.defaults</path>
312     (<path>/etc/make.profile</path> should actually be a symlink to,
313     <path>/usr/portage/profiles/default</path>),
314     which contains system profile-specific default settings. The priority order of
315     the various configuration files is as follows (highest first):
316     <ol>
317     <li>Environment variables</li>
318     <li><path>/etc/make.conf</path>, for your use</li>
319     <li><path>/etc/make.profile/make.defaults</path>, for profile-specific defaults</li>
320     <li><path>/etc/make.globals</path>, for global defaults (settings not specified in
321     any other place come from here)</li>
322     </ol></p></body>

325     <section>
326     <title>Is there a way to upgrade all installed packages
327     e.g. <e>apt-get upgrade</e> or <e>make World</e>?</title>
328     <body><p><b>YES!</b> Type <c>emerge --update system</c> (use it with <c>--pretend</c> first) to
329     update all core system packages, and use <c>emerge --update world</c> (again, use it with
330     <c>--pretend</c> first) to do a complete system upgrade of all installed packages.

336     <section>
337     <title>When updating a package using <c>emerge</c> or <c>ebuild</c>, how do I avoid
338     clobbering my config files?</title>
339     <body><p>
340     Portage now includes config file management support by default. Type
341     <c>emerge --help config</c> for more details. The (overly) simple answer is that if
342     a package installs <path>foo</path> somewhere under <path>/etc</path>, and
343     another <path>foo</path> already exists there, then the new <path>foo</path> will
344     instead be renamed to <path>._cfgxxxx_foo</path> in that directory. A useful
345     tool for examining and updating any protected config files is <c>etc-update</c>,
346     currently obtained by <c>emerge app-admin/gentoolkit</c>.
347     </p></body>
348     </section>
350     <section>
351     <title>I want to perform the <c>./configure</c> step myself. Can I?</title>
352     <body><p>
353     Yes, but it is not trivial. First do <c>man ebuild</c> followed by
354     <c>ebuild foo-x.y.z.ebuild unpack</c>. Then <c>cd</c> to
355     <path>/var/tmp/portage/foo-x.y.z/work</path>. You can manually perform
356     the <c>./configure</c> and <c>make</c> steps yourself (you'll have to do
357     both, since Portage does not separate the configure and build steps). To
358     have Portage finish the installation (so that you can easily remove it later,
359     should you desire to do so, and it will be registered in Portage as a possible
360     dependency) you first need to <c>touch /var/tmp/portage/foo-x.y.z/.compiled</c>
361     (tricking Portage into thinking that <c>ebuild foo-x.y.z.ebuild compile</c> has
362     completed), followed by <c>ebuild foo-x.y.z.ebuild merge</c>.

367     <title>What if rsync doesn't work for me?</title>
368     <body><p>
369     If you're behind a firewall that doesn't permit
370     rsync traffic, then you can instead download the daily
371 seo 1.12 /usr/portage snapshots from
372     <uri>http://cvs.gentoo.org/snapshots/</uri>. Just unpack
373 drobbins 1.1 the tarball (using <c>tar xvjf portage-foo.tbz2</c>) in
374     the <path>/usr</path> directory.

378     <section>
379     <title>How do I use <i>emerge</i> from behind a firewall?</title>
380     <body><p>
381     Edit the PROXY settings in <path>/etc/make.conf</path>. If that doesn't work,
382     edit <path>/etc/wget/wgetrc</path> and edit http_proxy and ftp_proxy
383     appropriately.

394     <title>I have only slow modem connection at home. Can I download sources somewhere else and

397     Definitely. You can run <c>emerge --pretend package</c> to see what programs
398 peesh 1.24 are going to be installed. To find out the sources for those packages and where to
399     download the sources from, you can run <c>emerge -fp package</c>.
400     Download sources and bring them on any media
401 drobbins 1.1 home. Put the sources into <path>/usr/portage/distfiles</path> and run
402     <c>emerge package</c> to see it picking up the sources you just brought in!

409     <body><p>
410     Yes, you can safely delete these files. But if you are on a slow
411     connection, such as a modem, you might want to keep the archives if
412     possible; often several ebuilds will be released for the same version of
413     a specific piece of software - if you have deleted the archive and you
414     upgrade the software it will have to be downloaded from the internet
415     again.

422     <p>The simplest method is to use anonymous CVS instead of rsync, and
423     maintain your local
424     ebuilds in /usr/portage/local. Here's how to do it:</p>

471     This is most probably because your user account doesn't have a valid shell specified. Check

474     you must set a shell for the user. This is done using the usermod command, like this ;

604     Console beeps can be turned off using setterm, like this ;

608     If you would like to turn off the console beeps on boot
609     you need to put this command in

611     disables beeps for the current terminal. To disable
612     beeps for other terminals, pipe the command output to the
613     target terminal, like this ;
615     <pre># <i>setterm -blength 0 >/dev/vc/1</i></pre>
617     You need to replace /dev/vc/1 with the terminal

648     <title>Why, when I hit reply to a post on a Gentoo mailing list, does my answer
649     only go to the original poster and not the entire list?</title>
650     <body>
651     <p>The mailing list administrators have decided to go with minimal munging
652     (altering of mail headers), which means that they have decided against
653     altering headers to have replies go to the mailing list. There are various
654     reasons for this. For example, if a subscriber has a full mailbox, the
655     entire list receives notice of this every time that something is posted.
657     Most GUI based mailers have a "reply to all" function. This will ensure that
658     your reply goes to the mailing list as well as the original poster. Most
659     users of text based emailers already know the methods to use, but if you
660     don't, in Pine, there is a "reply to group" option. Setting Mutt to reply to
661     the list is covered in the unofficial documentation at
662     <uri link="http://forums.gentoo.org/viewtopic.php?t=1085">forums.gentoo.org</uri>.
664     Some list members do not like this method, but it was very heavily
665     discussed when it went into effect, with arguments on both sides.
666     Eventually the list administrators decided to keep it this way. Discussing
667     it on the mailing list will sometimes bring a polite explanation and other
668     times a rather brusque comment to check the archives. Although the
669     administrators regret the inconvenience that it may cause some users, it is
670     felt that at present it is preferable to the alternative for several
671     reasons, many of these covered
672     <uri link="http://www.unicom.com/pw/reply-to-harmful.html">here</uri>.
674     (There are other eloquent arguments in favor of munging, and yes, the list
675     administrators have seen them.) </p>
