If you are booted from a x86 or ppc CD-1 LiveCD you can relax and continue with |
| 427 |
<uri link="?part=1&chap=7">Configuring the Kernel</uri> as the installation |
| 428 |
of prebuilt packages happens at the very end of the installation. |
| 429 |
</p> |
| 430 |
|
| 431 |
<p> |
| 432 |
If you are booted from a different architecture LiveCD and you want to use the |
| 433 |
prebuilt packages provided by the LiveCD, continue with <uri |
| 434 |
link="#copying_from_livecd">Copying over the GRP packages</uri>. |
| 435 |
</p> |
| 436 |

If you want to use the prebuilt packages provided by a Gentoo mirror, continue |
| 439 |
with <uri link="#grp_downloads">Configuring Portage for GRP Downloads</uri>. |

| 447 |
|
| 448 |
<p> |
| 449 |
You should now copy over the packages onto your filesystem so that Portage is |
| 450 |
able to use them. First of all, open a second terminal by pressing |
| 451 |
<c>Alt-F2</c>. This is needed as we need to work from the LiveCD, not from the |
| 452 |
chrooted environment you're currently working in. |
| 453 |
</p> |
| 454 |
|
| 455 |
<p> |
| 456 |
You should be greeted by a root prompt (<c>#</c>). Copy over the packages using |
| 457 |
the following commands: |
| 458 |
</p> |
| 459 |
|
| 460 |
<pre caption="Copy over precompiled packages"> |
| 461 |
# <i>mkdir -p /mnt/gentoo/usr/portage/packages/All</i> |
| 462 |
# <i>cp /mnt/cdrom/packages/All/* /mnt/gentoo/usr/portage/packages/All/</i> |
| 463 |
</pre> |
| 464 |
|
| 465 |
<p> |
| 466 |
After this step has completed, return to the chrooted environment by pressing |
| 467 |
<c>Alt-F1</c>. |
| 468 |
</p> |
| 469 |
|
| 470 |
<p> |
| 471 |
Now pay close attention! Your Portage snapshot is in place and the GRP packages |
| 472 |
are ready to be used. However, Portage doesn't automagically use them unless you |
| 473 |
tell it to. Luckily, this is hardly difficult: every time you are asked to |
| 474 |
install a package using <c>emerge</c>, you must add <c>--usepkg</c> as an |
| 475 |
option: |
| 476 |

That's all there is to it. Just don't forget to add <c>--usepkg</c>. Now |

| 499 |
First of all, you need to edit <path>/etc/make.conf</path> and define |
| 500 |
the <c>PORTAGE_BINHOST</c> variable so that it points to the server from which |
| 501 |
you want to download the GRP packages. Please check our <uri |
| 502 |
link="/main/en/mirrors.xml">mirror list</uri> for the available mirrors. |
| 503 |
</p> |
| 504 |
|
| 505 |
<pre caption="Editing /mnt/gentoo/etc/make.conf"> |
| 506 |
# <i>nano -w /etc/make.conf</i> |
| 507 |
</pre> |
| 508 |
|
| 509 |
<pre caption="Setting the PORTAGE_BINHOST variable"> |
| 510 |
PORTAGE_BINHOST="ftp://some.mirror.com/pub/gentoo/grp/2004/athlon-xp" |
| 511 |
</pre> |
| 512 |
|
| 513 |
<p> |
| 514 |
Save and exit (by pressing Ctrl-X and confirming). With this in place, you must |
| 515 |
now pay close attention. Portage will not automagically download the GRP |
| 516 |
packages if you don't instruct it to. However, this isn't hard: every time you |
| 517 |
are asked to install a package using <c>emerge</c>, you must add |
| 518 |
<c>--getbinpkg</c> as an option: |
| 519 |
