28 <p>Gentoo Linux is a fast, modern distribution with a clean and flexible 92
29 design -- in this respect, Gentoo may appeal to 93<p>

104</p>
105
106<p>
107With Gentoo you can build your entire system from source, using your choice of
108optimizations. You have complete control over what packages are or aren't
109installed. Gentoo provides you with numerous choices, so you can install Gentoo
110to your own preferences, which is why Gentoo is called a <e>meta-distribution</e>.
111</p>
112
113<p>
114Gentoo is actively developed. The entire distribution uses a rapid pace
115development style: patches to the packages are quickly integrated in the
116mainline tree, documentation is updated on daily basis, Portage features are
117added frequently, and official releases occur twice per year.

58 and installing from within the minimal linux environment provided by 145</body>
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>

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.

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>

157 <p>Under Gentoo Linux 1.0_rc6 and later, you can disable devfs by passing the 227
158 <c>gentoo=nodevfs</c> to the kernel.</p> 228<p>
229You don't need to redo every step of the installation, but investigating the
230kernel and all associated steps is necessary. Suppose you have installed Gentoo
231on <path>/dev/sda1</path> (/boot) and <path>/dev/sda3</path> (/) with
232<path>/dev/sda2</path> being the swap space:

261If, on the other hand, the problem lies with your bootloader configuration,
262follow the same steps, but instead of configuring/compiling your kernel, you

295There are lots of CD burning tools available; covering them all would be a
296Sisyphean problem. However, describing a few popular tools never hurts:
297</p>
298
299<ul>
300 <li>
301 With EasyCD Creator you select <c>File</c>, <c>Record CD
302 from CD image</c>. Then you change the <c>Files of type</c> to <c>ISO image
303 file</c>. Then locate the ISO file and click <c>Open</c>. When you click on
304 <c>Start recording</c> the ISO image will be burned correctly onto the CD-R.
305 </li>
306 <li>
307 With Nero Burning ROM, cancel the wizard which automatically pops up and
308 select <c>Burn Image</c> from the <c>File</c> menu. Select the image you
309 want to burn and click <c>Open</c>. Now hit the <c>Burn</c> button and watch
310 your brand new CD being burnt.
311 </li>
312 <li>
313 With cdrecord, you simply type <c>cdrecord dev=/dev/sdc</c> (replace
314 <path>/dev/sdc</path> with your CD-RW drive's device path) followed
315 by the path to the ISO file :)
316 </li>
317 <li>

344need to find out what CPU it is, instruction-wise, compatible with. You may

350If you are uncertain, take a "lower" CD/stage file, for instance a i686 or even

403<p>
404This is a known problem. Windows refuses to boot when it isn't installed on the

406to "fool" Windows into believing that it is installed on the first hard drive
407with a little tweak in your boot loader configuration. Please note that in the
408below example, Gentoo is installed on <path>sda</path> (first disk) and Windows
409on <path>sdb</path> (second one). Adjust your config as needed.

440<title>How do I Install Gentoo Using a Stage1 or Stage2 Tarball?</title>
441<body>
442
443<p>
444The Gentoo Handbook only describes a Gentoo installation using a stage3 tarball.
445However, Gentoo still provides stage1 and stage2 tarballs. This is for
446development purposes (the Release Engineering team starts from a stage1 tarball
447to obtain a stage3) but shouldn't be used by users: a stage3 tarball can very
448well be used to bootstrap the system. You do need a working Internet connection.
449</p>
450
451<p>
452Bootstrapping means building the toolchain (the C library and compiler) for
453your system after which you install all core system packages. To bootstrap the
454system, perform a stage3 installation. Before you start the chapter on
455<e>Configuring the Kernel</e>, modify the <path>bootstrap.sh</path> script to
456suit your needs and then run it:
457</p>
458
459<pre caption="Bootstrapping the system">
460# <i>cd /usr/portage/scripts</i>
461# <i>vi bootstrap.sh</i>
462
463# <i>./bootstrap.sh</i>
464</pre>
465
466<p>
467Next, rebuild all core system packages with the newly built toolchain. We need
468to rebuild them since the stage3 tarball already offers them:
469</p>
470
471<pre caption="Rebuilding the core system packages">
472# <i>emerge -e system</i>
473</pre>
474
475<p>
476Now you can continue with <e>Configuring the Kernel</e>. You can not use the
477prebuilt GRP packages anymore though.

329 Portage now includes config file management support by default. Type

331 a package installs <path>foo</path> somewhere under <path>/etc</path>, and
332 another <path>foo</path> already exists there, then the new <path>foo</path> will
333 instead be renamed to <path>._cfgxxxx_foo</path> in that directory. A useful

343 <c>ebuild foo-x.y.z.ebuild unpack</c>. Then <c>cd</c> to
344 <path>/var/tmp/portage/foo-x.y.z/work</path>. You can manually perform
345 the <c>./configure</c> and <c>make</c> steps yourself (you'll have to do
346 both, since Portage does not separate the configure and build steps). To
347 have Portage finish the installation (so that you can easily remove it later,
348 should you desire to do so, and it will be registered in Portage as a possible
349 dependency) you first need to <c>touch /var/tmp/portage/foo-x.y.z/.compiled</c>
350 (tricking Portage into thinking that <c>ebuild foo-x.y.z.ebuild compile</c> has
351 completed), followed by <c>ebuild foo-x.y.z.ebuild merge</c>.

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.
630
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>.
637
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>.

649 administrators have seen them.) </p>
