Handbook:Parts/Installation/About/ja

ようこそ
まずはじめに、Gentoo へようこそ. あなたは、選択と性能の世界に入ろうとしています. Gentoo では、全てが選択です. そのことは、インストールするときにもたびたび明らかになります. コンパイルを何回やらせたいか、Gentoo をどのようにインストールしたいか、システムのロギングツールに何を使用したいかなどなど、ユーザーに選択権があります.

Gentoo は、高速で現代的なメタディストリビューションで、整理された柔軟なデザインになっています. Gentoo は、フリーソフトウェアで造られており、内部をユーザに隠匿することがありません. Gentoo で用いるパッケージ管理システムである Portage は Python で書かれていますので、ソースコードを容易に閲覧したり改変したりすることができます. Gentoo で採用しているパッケージ化の手法は、（コンパイル済パッケージにも対応していますが、）ソースコードを用いるものです. Gentoo の設定は、一般的なテキストファイルで行います. つまり言い換えれば、Gentoo は、全てをユーザーに開放しています.

Gentoo に実行させることの選択肢を全員が理解していることは、きわめて重要です. 望まざることをユーザーに強いないよう、我々は努めています. もしかりにこれに反するようなことがあったならば、バグリポートを送ってください.

インストール作業の順序
The Gentoo Installation can be seen as a 10-step procedure, corresponding to the next set of chapters. Every step results in a certain state:
 * 1) After step 1, the user is in a working environment ready to install Gentoo
 * 2) After step 2, the Internet connection is ready to install Gentoo
 * 3) After step 3, the hard disks are initialized to host the Gentoo installation
 * 4) After step 4, the installation environment is prepared and the user is ready to chroot into the new environment
 * 5) After step 5, core packages, which are the same on all Gentoo installations, are installed
 * 6) After step 6, the Linux kernel is installed
 * 7) After step 7, the user will have configured most of the Gentoo system configuration files
 * 8) After step 8, the necessary system tools are installed
 * 9) After step 9, the proper boot loader has been installed and configured
 * 10) After step 10, the freshly installed Gentoo Linux environment is ready to be explored

Whenever a certain choice is presented, the handbook will try to explain what the pros and cons are. Although the text then continues with a default choice (identified by "Default: " in the title), the other possibilities will be documented as well (marked by "Alternative: " in the title). Do not think that the default is what Gentoo recommends. It is however what Gentoo believes most users will use.

Sometimes an optional step can be followed. Such steps are marked as "Optional: " and are therefore not needed to install Gentoo. However, some optional steps are dependent on a previous decision made. The instructions will inform the reader when this happens, both when the decision is made, and right before the optional step is described.

What are the options
Gentoo can be installed in many different ways. It can be downloaded and installed from one of Gentoo's Installation CDs, from a distribution already installed, from a non-Gentoo bootable CD (such as Knoppix), from a netbooted environment, from a rescue floppy, etc.

This document covers the installation using a Gentoo Installation CD or, in certain cases, netbooting.

We also provide a Gentoo Installation Tips & Tricks document that might be useful to read as well.

Troubles
If a problem is found in the installation (or in the installation documentation), please visit our bugtracking system and check if the bug is known. If not, please create a bugreport for it so we can take care of it. Do not be afraid of the developers who are assigned to the bugs -- they (generally) don't eat people.

Note though that, although this document is architecture-specific, it might contain references to other architectures as well. This is due to the fact that large parts of the Gentoo Handbook use source code that is common for all architectures (to avoid duplication of efforts and starvation of development resources). We will try to keep this to a minimum to avoid confusion.

If there is some uncertainty whether or not the problem is a user-problem (some error made despite having read the documentation carefully) or a software-problem (some error we made despite having tested the installation/documentation carefully) everybody is welcome to join #gentoo on irc.freenode.net. Of course, everyone is welcome otherwise too as our chat channel covers the broad Gentoo spectrum :)
