<h1>ファイルシステムの設計</h1>
<p>Haikuのファイルシステムの設計は完全に透過的で、ファイルやフォルダーに暗号めいていない名前を使うよう常に努力しています。
システムが正しく機能するために重要なファイルやフォルダーについては、次のような警告を表示することで不慮の操作からそれらを保護します:</p>
<img src="images/filesystem-layout-images/achtung-user.png" alt="achtung-user.png" /> 
<img src="images/filesystem-layout-images/achtung-system.png" alt="achtung-system.png" />
<p>システム階層下の何かをリネームまたは削除しようとすると、第二の警告が表示されます。 "<span class="button">Rename</span>" ボタンは <span class="key">SHIFT</span> キーを押している間だけクリックできます。</p>
<p>Generally, there are two separate branches springing from the root folder of the boot volume:</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="2">
<tr><td><span class="path">/boot/system/</span></td><td> </td><td>Contains system files and applications/packages shared by all users.</td></tr>
<tr><td><span class="path">/boot/home/</span></td><td> </td><td>This is your personal folder where you keep your data and settings and the applications/packages that are <i>not</i> shared by all users.</td></tr>
</table>
<p>As long as Haiku isn't multi-user, this distinction between shared and not-shared applications/packages has no apparent effect, as there's only one user with one home folder. But since there will be support for more users than one eventually, it makes sense to learn the right way from the start.</p>
<h2>
<a href="#"><img src="../images/up.png" style="border:none;float:right" alt="index" /></a>
<a id="system" name="system">システムフォルダー - <span class="path">/boot/system/</span></a></h2>
<p>Under Haiku's predecessor BeOS, this folder was named <span class="path">/boot/beos/</span>. You may still find it in some older documentation (e.g. in the original BeBook).<br />
Most of the folders inside <span class="path">/boot/system/</span> are read-only, which is sensible as they contain the files necessary for Haiku to function correctly and therefore have to be safe from (accidental) alteration. The only user-writable folders are:</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="2">
<tr><td><span class="path">/boot/system/cache/</span></td><td> </td><td>Contains cached files and the temporary folder linked to <span class="path">/tmp/</span>.</td></tr>
<tr><td class="onelinetop"><span class="path">/boot/system/non-packaged/</span></td><td> </td><td>Contains a hierarchy for files that aren't part of a .hpkg (probably from old BeOS archives).</td></tr>
<tr><td><span class="path">/boot/system/packages/</span></td><td> </td><td>Besides holding Haiku's system packages, you can add/remove packages shared by all users.</td></tr>
<tr><td><span class="path">/boot/system/settings/</span></td><td> </td><td>Contains system-wide settings.</td></tr>
<tr><td><span class="path">/boot/system/var/</span></td><td> </td><td>Contains logs like the syslog (important when troubleshooting) and is the default location for the swap file.</td></tr>
</table>
<p><span class="box-info">For more information on the <span class="path">packages</span> and <span class="path">non-packaged</span> folders, see topic <a href="">Installing applications</a>.</span></p>
<h2>
<a href="#"><img src="../images/up.png" style="border:none;float:right" alt="index" /></a>
<a id="home" name="home">ホームフォルダー - <span class="path">/boot/home/</span></a></h2>
<p>This folder belongs to you. Here you can create and delete files and folders as you wish. (By the way, the tilde ("<tt>~</tt>") is a shortcut for your home folder, so you don't always have to write "<span class="path">/boot/home/</span>" in Terminal.)<br />
Files that you'd like to share with other users in a future multi-user environment have do be put outside <span class="path">/boot/home/</span>. For example, you could create a folder <span class="path">/boot/all-users/</span> and put the stuff there.</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="4">
<tr><td><span class="path">~/Desktop/</span></td><td style="width:10px;"> </td>
<td>Holds the files of your desktop. Double-clicking won't open it, as it is already always visible. When your files happen to be obscured by open windows, just switch quickly to another <a href="workspaces.html">Workspace</a>. Of course, <a href="tracker.html#drill-down">drilling</a> down by right-clicking is also possible.</td></tr>
<tr><td><span class="path">~/mail/</span></td><td style="width:10px;"> </td>
<td>This is the default location for your mails.</td></tr>
<tr><td><span class="path">~/people/</span></td><td style="width:10px;"> </td>
<td>This is the default location for you contact files, see <a href="applications/people.html">People</a>.</td></tr>
<tr><td><span class="path">~/queries/</span></td><td style="width:10px;"> </td>
<td><a href="queries.html">Queries</a> are stored here, by default temporarily for 7 days.</td></tr>
</table>
<p>The folder <span class="path">/boot/home/config/</span> is special: just like <span class="path">/boot/system/</span> it's mostly under the control of the package management and therefore read-only. It too contains these similar user-writable folders:</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="4">
<tr><td><span class="path">~/config/packages/</span></td><td style="width:10px;"> </td>
<td>Here you can add/remove packages that are <i>not</i> shared by all users.</td></tr>
<tr><td class="onelinetop"><span class="path">~/config/non-packaged/</span></td><td> </td>
<td>Contains a hierarchy for files that aren't part of a .hpkg (probably from old BeOS archives) and are <i>not</i> shared by all users.</td></tr>
<tr><td><span class="path">~/config/settings/</span></td><td> </td>
<td>このフォルダーは、すべてのアプリケーションの設定と、システムに関する 2、3 の設定を含んでいます。個別のサブフォルダーによって設定を管理するアプリケーションと、単に設定ファイルを置くだけのアプリケーションがあります。</td></tr>
</table>
<p><span class="box-info">For more information on the <span class="path">packages</span> and <span class="path">non-packaged</span> folders, see topic <a href="">Installing applications</a>.</span></p>
<p>Here are some of the more interesting subfolders in <span class="path">~/config/settings</span>:</p>
<table summary="layout" border="0" cellspacing="0" cellpadding="4">
<tr><td><span class="path">boot/</span></td><td style="width:10px;"> </td>
<td>このフォルダーにはシステムのブート前またはシャットダウン後に実行される<a href="bash-scripting.html#user-scripts">ユーザスクリプト</a>が置かれます。</td></tr>
<tr><td><span class="path">boot/launch/</span></td><td> </td>
<td>このフォルダー下にあるプログラムやドキュメントへのリンクは、ブートごとに自動で起動します。</td></tr>
<tr><td><span class="path">beos_mime/</span></td><td> </td>
<td>この <acronym title="Multipurpose Internet Mail Extensions">MIME</acronym> データベースで、 Haiku はすべての異なる<a href="filetypes.html">ファイルタイプ</a>、およびそれらの設定を管理します。</td></tr>
<tr><td class="onelinetop"><span class="path">deskbar/menu/</span></td><td> </td>
<td>Copied or linked to files/folders/queries in this folder appear in the <a href="deskbar.html#deskbar-menu">Deskbar menu</a>.</td></tr>
<tr><td class="onelinetop"><span class="path">kernel/drivers/</span></td><td> </td>
<td>興味を引きそうな設定ファイルである <span class="cli">kernel</span> は、 <acronym title="Symmetric Multi Processing">SMP</acronym> を無効にする、シリアルデバッギングを有効にする、あるいは高度な電源管理を可能にするといったいくつかの低レベルの設定を提供します。コメント記号 "<tt>#</tt>" を削除することで設定行が有効になります。このフォルダー内では慎重になってください!</td></tr>
<tr><td><span class="path">Tracker/</span></td><td> </td>
<td>ここには、 Tracker のための様々な設定ファイルに加え、興味を引くサブフォルダがいくつかあります:</td></tr>
<tr><td align="right"><span class="path">DefaultFolderTemplate/</span></td><td style="width:10px;"></td><td>すべての属性とウィンドウサイズを好きなように表示、アレンジできます。作成されるすべての新規フォルダーがテンプレートとしてそれを使用します。</td></tr>
<tr><td align="right"><span class="path">DefaultQueryTemplates/</span></td><td></td><td>特定のファイルタイプのためのクエリ結果ウィンドウのレイアウトを定義できます。トピック<a href="queries.html#result-window">クエリ: 結果ウィンドウ</a>を参照してください。</td></tr>
<tr><td align="right"><span class="path">Go/</span></td><td></td><td>例えば、読込/保存パネルでリンクが利用できるようにするといった目的で、このフォルダーの中にユーザの使いたい場所へのリンクを置きます。トピック <a href="gui.html#favorites-recent">Haiku の GUI Favorites および Recent フォルダー</a>を参照してください。</td></tr>
<tr><td align="right"><span class="path">Tracker New Template/</span></td><td></td><td>Tracker の <span class="menu">File | New...</span> メニューから利用可能なあらゆるファイルタイプのためのテンプレートを追加します。トピック <a href="tracker.html#working-with-files">Tracker: Working with files</a> を参照してください。</td></tr>
