<abstract>
As times goes by, Portage evolves and matures further and further. Additional
features are continuously being put in - many of these are only of use by more
advanced users. This chapter will go into more detail of these specific
features.
</abstract>

<version>1</version>

<section>
<title>Introduction</title>
<body>

<p>
For most users, the information received thus far is sufficient for all their
Linux operations. But Portage is capable of much more; many of its features are
for advanced users or only applicable in specific corner cases. Still, that
would not be an excuse not to document them.
</p>

<p>
Of course, with lots of flexibility comes a huge list of potential cases. It
will not be possible to document them all here. Instead, we hope to focus on
some generic issues which you can then bend to fit your own needs. If you have
need for more specific tweaks and tips, you might find them on the <uri
link="https://wiki.gentoo.org">Gentoo WiKi</uri> instead.
</p>

<p>
Most, if not all of these additional features can be easily found by digging
through the manual pages that portage provides:
</p>

<pre caption="Reading up on portage man pages">
$ <i>man portage</i>
$ <i>man make.conf</i>
</pre>

<p>
Finally, know that these are advanced features which, if not worked with
correctly, can make debugging and troubleshooting very difficult. Make sure you
mention these if you think you hit a bug and want to open a bugreport.
</p>

<section>
<title>Per-Package Environment Variables</title>
<subsection>
<title>Using /etc/portage/env</title>
<body>

<p>
By default, package builds will use the environment variables defined in
<path>/etc/make.conf</path>, such as <c>CFLAGS</c>, <c>MAKEOPTS</c> and more. In
some cases though, you might want to provide different variables for specific
packages. To do so, Portage supports the use of <path>/etc/portage/env</path>
and <path>/etc/portage/package.env</path>.
</p>

<p>
The <path>/etc/portage/package.env</path> file contains the list of packages for
which you want deviating variables as well as a specific identifier that tells
Portage which changes you want. The identifier name you pick yourself, Portage
will look for the variables in the <path>/etc/portage/env/&lt;identifier&gt;</path>
file.
</p>

</body>
</subsection>
<subsection>
<title>Example: Using debugging for specific packages</title>
<body>

<p>
As an example, we enable debugging for the <path>media-video/mplayer</path>
package.
</p>

<p>
First of all, we set the debugging variables in a file called
<path>/etc/portage/env/debug-cflags</path>. The name is arbitrarily chosen, but
of course reflects the reason of the deviation to make it more obvious later why
a deviation was put in.
</p>

<pre caption="/etc/portage/env/debug-cflags content">
CFLAGS="-O2 -ggdb -pipe"
FEATURES="${FEATURES} nostrip"
</pre>

<p>
Next, we tag the <path>media-video/mplayer</path> package to use this content:
</p>

<pre caption="/etc/portage/package.env content">
media-video/mplayer debug-cflags
</pre>

<section>
<title>Hooking In the Emerge Process</title>
<subsection>
<title>Using /etc/portage/bashrc and affiliated files</title>
<body>

<p>
When Portage works with ebuilds, it uses a bash environment in which it calls
the various build functions (like src_prepare, src_configure, src_postinst,
etc.). But Portage also allows you to set up a bash environment yourself.
</p>

<p>
The advantage of using your own bash environment is that you can hook in the
emerge process during each step it performs. This can be done for every emerge
(through <path>/etc/portage/bashrc</path>) or by using per-package environments
(through <path>/etc/portage/env</path> as discussed earlier).
</p>

<p>
To hook in the process, the bash environment can listen to the variables
<c>EBUILD_PHASE</c>, <c>CATEGORY</c> as well as the variables that are always
available during ebuild development (such as <c>P</c>, <c>PF</c>, ...). Based on
the values of these variables, you can then execute additional steps.
</p>

</body>
</subsection>
<subsection>
<title>Example: Updating File Databases</title>
<body>

<p>
In this example, we'll use <path>/etc/portage/bashrc</path> to call some file
database applications to ensure their databases are up to date with the system.
The applications used in the example are <c>aide</c> (an intrusion detection
tool) and <c>updatedb</c> (to use with <c>locate</c>), but these are meant as
examples. Do not consider this as a HOWTO for AIDE ;-)
</p>

<p>
To use <path>/etc/portage/bashrc</path> for this case, we need to "hook" in the
<c>postrm</c> (after removal of files) and <c>postinst</c> (after installation
of files) functions, because that is when the files on the file system have been
changed.
</p>

<pre caption="Example /etc/portage/bashrc">
if [ "${EBUILD_PHASE}" == "postinst"] || [ "${EBUILD_PHASE}" == "postrm" ];
then
  echo ":: Calling aide --update to update its database";
  aide --update;
  echo ":: Calling updatedb to update its database";
  updatedb;
fi
</pre>

</body>

<section>
<title>Executing Tasks After --sync</title>
<subsection>
<title>The /etc/portage/postsync.d location</title>
<body>

<p>
Until now we've talked about hooking into the ebuild processes. However, Portage
also has another important function: updating the Portage tree. In order to run
tasks after updating the Portage tree, put a script inside
<path>/etc/portage/postsync.d</path> and make sure it is marked as executable.
</p>

</body>
</subsection>
<subsection>
<title>Example: Running eix-update</title>
<body>

<p>
If you didn't use <c>eix-sync</c> to update the tree, you can still have its
database updated after running <c>emerge --sync</c> (or <c>emerge-webrsync</c>)
by putting a symlink to <path>/usr/bin/eix</path> called <path>eix-update</path>
in <path>/etc/portage/postsync.d</path>.
</p>

<pre caption="Running eix-update after a sync operation">
# <i>ln -s /usr/bin/eix /etc/portage/postsync.d/eix-update</i>
</pre>

<note>
If you rather use a different name, you will need to make a script that calls
<c>/usr/bin/eix-update</c> instead. The <c>eix</c> binary looks at how it has
been called to find out which function it has to execute. If you put in a
symlink to <c>eix</c> that isn't called <c>eix-update</c>, it will not run
correctly.
</note>

<section>
<title>Overriding Profile Settings</title>
<subsection>
<title>The /etc/portage/profile location</title>
<body>

<p>
By default, Gentoo uses the settings contained in the profile pointed to by
<path>/etc/make.profile</path> (a symbolic link to the right profile directory).
These profiles define both specific settings as well as inherit settings from
other profiles (through their <path>parent</path> file).
</p>

<p>
By using <path>/etc/portage/profile</path>, you can override profile settings
such as <path>packages</path> (what packages are considered to be part of the
system set), <path>virtuals</path> (default packages when pulling in a virtual)
and more.
</p>

</body>
</subsection>
<subsection>
<title>Example: Adding nfs-utils to the System Set</title>
<body>

<p>
If you use NFS-based file systems for rather critical file systems, you might
want to have <path>net-fs/nfs-utils</path> "protected" as a system package,
causing Portage to heavily warn you if it would be deleted.
</p>

<p>
To accomplish that, we add the package to
<path>/etc/portage/profile/packages</path>, prepended with a <c>*</c>:
</p>

<pre caption="/etc/portage/profile/packages content">
*net-fs/nfs-utils
</pre>

<section>
<title>Applying Non-Standard Patches</title>
<subsection>
<title>Using epatch_user</title>
<body>

<p>
To manage several ebuilds in a similar manner, ebuild developers use
<e>eclasses</e> (sort-of shell libraries) that define commonly used functions.
One of these eclasses is <path>eutils.eclass</path> which offers an interesting
function called <c>epatch_user</c>.
</p>

<p>
The <c>epatch_user</c> function applies source code patches that are found in
<path>/etc/portage/patches/&lt;category&gt;/&lt;package&gt;[-&lt;version&gt;[-&lt;revision&gt;]]</path>,
whatever directory is found first. Sadly, not all ebuilds automatically call
this function so just putting your patch in this location might not always work.
</p>

<p>
Luckily, with the information provided above, you can call this function by
hooking into, for instance, the <c>prepare</c> phase. The function can be called
as many times as you like - it will only apply the patches once.
</p>

</body>
</subsection>
<subsection>
<title>Example: Applying Patches to Firefox</title>
<body>

<p>
The <path>www-client/firefox</path> package is one of the few that already call
<c>epatch_user</c> from within the ebuild, so you do not need to override
anything specific. 
</p>

<p>
If you need to patch firefox (for instance because a developer asked you to to
support you in a bug you reported), put the patch in
<path>/etc/portage/patches/www-client/firefox</path> (probably best to use the
full name, including version so that the patch does not interfere with later
versions) and rebuild firefox.
</p>
