<h1>Filesystem layout</h1>
|
||
|
||
<p>Haiku's filesystem layout is quite transparent, trying to always use non-cryptic names for files and folders, that don't leave the user guessing. Files and folders that are important for the system to function properly, are protected from accidental tempering by showing one of these alerts:</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>The second alert pops up if you try to rename or delete something in the system hierarchy. Here, the "<span class="button">Rename</span>" button will only become clickable when you're holding down the <span class="key">SHIFT</span> key.</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">The system folder - <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="applications.html">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">The home folder - <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>

<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">
