You first need to select your timezone so that your system knows where it is |
| 16 |
|
|
located. Look for your timezone in <path>/usr/share/zoneinfo</path>, then make a |
| 17 |
|
|
symlink to <path>/etc/localtime</path> using <c>ln</c>: |

The core around which all distributions are built is the Linux kernel. It is the |
| 36 |
|
|
layer between the user programs and your system hardware. Gentoo provides its |
| 37 |
|
|
users several possible kernel sources. A full listing with description is |
| 38 |
|
|
available at the <uri link="/doc/en/gentoo-kernel.xml">Gentoo Kernel |
| 39 |
|
|
Guide</uri>. |

</p> |

|
|
|
| 42 |
|
|
<p> |
| 43 |
|
|
For alpha-based systems we have <c>vanilla-sources</c> (the default kernel |
| 44 |
|
|
source as developed by the linux-kernel developers), <c>alpha-sources</c> |
| 45 |
|
|
(kernel source optimized for alpha users) and <c>compaq-sources</c> (kernel |
| 46 |
|
|
source as used by RedHat for Alpha, maintained by Compaq). |
| 47 |
|
|
</p> |
| 48 |
|
|
|
| 49 |
|
|
<p> |
| 50 |
|
|
Choose your kernel source and install it using <c>emerge</c>. |
| 51 |
|
|
</p> |
| 52 |
|
|
|
| 53 |
|
|
<p> |
| 54 |
|
|
In the next example we install the <c>vanilla-sources</c>. |
| 55 |
|
|
Of course substitute with your choice of sources, this is merely an example: |
| 56 |

|

<p> |
| 63 |
|
|
When you take a look in <path>/usr/src</path> you should see a symlink called |
| 64 |
|
|
<path>linux</path> pointing to your kernel source: |
| 65 |
|
|
</p> |

<pre caption="Viewing the kernel source symlink"> |

|

</pre> |
| 71 |
|
|
|
| 72 |
|
|
<p> |
| 73 |
|
|
If this isn't the case (i.e. the symlink points to a different kernel source) |
| 74 |
|
|
change the symlink before you continue: |
| 75 |
|
|

Now it is time to configure and compile your kernel source. You |
| 85 |
|
|
can use <c>genkernel</c> for this, which will build a generic kernel as used |
| 86 |
|
|
by the LiveCD. We explain the "manual" configuration first though, as it is |
| 87 |
|
|
the best way to optimize your environment. |

<c>genkernel</c> you should read <uri link="#genkernel">Alternative: Using |

Manually configuring a kernel is often seen as the most difficult procedure a |
| 108 |
neysx |
1.8 |
Linux user ever has to perform. Nothing is less true -- after configuring a |
| 109 |
swift |
1.1 |
couple of kernels you don't even remember that it was difficult ;) |
| 110 |
|
|
</p> |
| 111 |
|
|
|
| 112 |
|
|
<p> |
| 113 |
|
|
However, one thing <e>is</e> true: you must know your system when you start |
| 114 |
|
|
configuring a kernel manually. Most information can be gathered by viewing the |
| 115 |
|
|
contents of <path>/proc/pci</path> (or by using <c>lspci</c> if available). You |
| 116 |
|
|
can also run <c>lsmod</c> to see what kernel modules the LiveCD uses (it might |
| 117 |
|
|
provide you with a nice hint on what to enable). |
| 118 |
|
|
</p> |
| 119 |
|
|
|
| 120 |
|
|
<p> |
| 121 |
|
|
Now go to your kernel source directory and execute <c>make menuconfig</c>. This |
| 122 |
|
|
will fire up an ncurses-based configuration menu. |
| 123 |
|
|
</p> |

You will be greeted with several configuration sections. We'll first list some |
| 132 |
|

options you must activate (otherwise Gentoo will not function, or not function |
| 133 |
|
|
properly without additional tweaks). |

The two compression options won't harm but are not definitely needed, neither |
| 206 |
|

does the <c>PPP over Ethernet</c> option, that might only be used by |

<c>rp-pppoe</c> when configured to do kernel mode PPPoE. |

<title>Alternative: Using genkernel</title> |

<p> |

|
|
If you are reading this section, you have chosen to use our <c>genkernel</c> |
| 336 |
|
|
script to configure your kernel for you. |
| 337 |
|
|
</p> |
| 338 |
|
|
|
| 339 |
|
|
<p> |
| 340 |
|
|
Now that your kernel source tree is installed, it's now time to compile your |
| 341 |
|
|
kernel by using our <c>genkernel</c> script to automatically build a kernel for |
| 342 |
|
|
you. <c>genkernel</c> works by configuring a kernel nearly identically to the |
| 343 |
|
|
way our LiveCD kernel is configured. This means that when you use |
| 344 |
|
|
<c>genkernel</c> to build your kernel, your system will generally detect all |
| 345 |
|
|
your hardware at boot-time, just like our Live CD does. Because genkernel |
| 346 |
|
|
doesn't require any manual kernel configuration, it is an ideal solution for |
| 347 |
|
|
those users who may not be comfortable compiling their own kernels. |
| 348 |
|
|
</p> |
| 349 |
|
|
|
| 350 |
|
|
<p> |
| 351 |
|
|
Now, let's see how to use genkernel. First, emerge the genkernel ebuild: |
| 352 |
|
|
</p> |
| 353 |
|
|
|
| 354 |
|
|
<pre caption="Emerging genkernel"> |
| 355 |
|
|
# <i>emerge genkernel</i> |
| 356 |
|
|
</pre> |
| 357 |
|
|
|
| 358 |
|
|
<p> |
| 359 |
|
|
Now, compile your kernel sources by running <c>genkernel all</c>. |
| 360 |
|
|
Be aware though, as <c>genkernel</c> compiles a kernel that supports almost all |
| 361 |
|
|
hardware, this compilation will take quite a while to finish! |
| 362 |
|
|
</p> |
| 363 |
|
|
|
| 364 |
|
|
<p> |
| 365 |
|
|
Note that, if your boot partition doesn't use ext2 or ext3 as filesystem you |
| 366 |
|
|
need to manually configure your kernel using <c>genkernel --menuconfig all</c> |
| 367 |
|
|
and add support for your filesystem <e>in</e> the kernel (i.e. <e>not</e> as a |
| 368 |
|
|
module). |
| 369 |
|
|

| 382 |
|

| 383 |
|
|

| 384 |
|
|
* |
| 385 |
|
|
* You MUST tell your bootloader to use the generated initrd |
| 386 |

|
|
* Do NOT report kernel bugs (configs included) as genkernel bugs. |
| 391 |
|
|
* Make sure you have the latest genkernel before reporting bugs |

Once <c>genkernel</c> completes, a kernel, full set of modules and |
| 398 |
|
|
<e>initial root disk</e> (initrd) will be created. We will use the kernel |
| 399 |
|
|
and initrd when configuring a boot loader later in this document. Write |
| 400 |
|
|
down the names of the kernel and initrd as you will need it when writing |
| 401 |
|
|
the bootloader configuration file. The initrd will be started immediately after |
| 402 |
|
|
booting to perform hardware autodetection (just like on the Live CD) before |
| 403 |
|
|
your "real" system starts up. |
| 404 |

<p> |
| 411 |
|
|
Now, let's perform one more step to get our system to be more like the Live |
| 412 |
|
|
CD -- let's emerge <c>hotplug</c>. While the initrd autodetects hardware that |
| 413 |
|
|
is needed to boot your system, <c>hotplug</c> autodetects everything else. |
| 414 |
|
|
To emerge and enable <c>hotplug</c>, type the following: |

If appropriate, you should emerge ebuilds for any additional hardware that is |

Beware though, some of these ebuilds might deal with big dependencies. To verify |

|
|
what packages will be installed by emerging an ebuild, use <c>emerge |
| 459 |
|
|
--pretend</c>. For instance, for the <c>xfree-drm</c> package: |

You should list the modules you want automatically loaded in |
| 474 |
|
|
<path>/etc/modules.autoload.d/kernel-2.4</path> (or <path>kernel-2.6</path>). |
| 475 |
|
|
You can add extra options to the modules too if you want. |

|
|
</p> |
| 477 |
|
|
|
| 478 |
|
|
<p> |
| 479 |
|
|
To view all available modules, run the following <c>find</c> command. Don't |
| 480 |
|
|
forget to substitute "<kernel version>" with the version of the kernel you |
| 481 |
|
|
just compiled: |

|
</pre> |
| 487 |
|
|
|
| 488 |
|
|
<p> |
| 489 |
|
|
For instance, to automatically load the <c>3c59x.o</c> module, edit the |
| 490 |
|
|
<path>kernel-2.4</path> or <path>kernel-2.6</path> file and enter the module |
| 491 |
|
|
name in it. |
