<p>A software package is a bundle of related programs that are ready for you to install.
|
|
When you download a source code archive, you have to configure, compile, and install it
|
|
by hand. With a software package, this has already been done for you. All that you have
|
|
to do is install the package. Another handy feature of using software packages is that it
|
|
is very easy to remove and upgrade them, if you so desire. Slackware comes with programs
|
|
for all your package management needs. You can install, remove, upgrade, make, and
|
|
examine packages very easily.</p>
|
|
|
|
<p>There's a myth that's been going around ever since RedHat debuted RedHat Package
|
|
Manager, that Slackware has no package management tool. This simply couldn't be further
|
|
from the truth. Slackware has always included a package manager, even before RedHat
|
|
existed. While not as full-featured or as ubiquitous as rpm (or for that matter deb), <tt
|
|
class="COMMAND">pkgtool</tt> and its associated programs are every bit as good at
|
|
installing packages as rpm. The truth about <tt class="COMMAND">pkgtool</tt> is not that
|
|
it doesn't exist, but that it doesn't do any dependency checking.</p>
|
|
|
|
<p>Apparently many people in the Linux community think that a packager manager must by
|
|
definition include dependency checking. Well, that simply isn't the case, as Slackware
|
|
most certainly does not. This is not to say that Slackware packages don't have
|
|
dependencies, but rather that its package manager doesn't check for them. Dependency
|
|
management is left up to the sysadmin, and that's the way we like it.</p>

<h1 class="SECT1"><a id="PACKAGE-MANAGEMENT-OVERVIEW"

name="PACKAGE-MANAGEMENT-OVERVIEW">18.1 Overview of Package Format</a></h1>
|
|
|
|
<p>Before learning the utilities, you should become familiar with the format of a
|
|
Slackware package. In Slackware, a package is simply a tar archive file that has been
|
|
compressed with <tt class="COMMAND">gzip</tt>. Packages are built to be extracted in the
|
|
root directory.</p>
|
|
|
|
<p>Here is a fictitious program and its example package:</p>
|
|
|
|
<table border="0" bgcolor="#E0E0E0" width="100%">
|
|
<tr>
|
|
<td>
|
|
<pre class="SCREEN">
|
|
./
|
|
usr/
|
|
usr/bin/
|
|
usr/bin/makehejaz
|
|
usr/doc/
|
|
usr/doc/makehejaz-1.0/
|
|
usr/doc/makehejaz-1.0/COPYING
|
|
usr/doc/makehejaz-1.0/README
|
|
usr/man/

|
|
</pre>
|
|
</td>
|
|
</tr>
|
|
</table>
|
|
|
|
<p>The package system will extract this file in the root directory to install it. An
|
|
entry in the package database will be created that contains the contents of this package
|
|
so that it can be upgraded or removed later.</p>
|
|
|
|
<p>Notice the <tt class="FILENAME">install/</tt> subdirectory. This is a special
|
|
directory that can contain a postinstallation script called <tt
|
|
class="FILENAME">doinst.sh</tt>. If the package system finds this file, it will execute
|
|
it after installing the package.</p>
|
|
|
|
<p>Other scripts can be embedded in the package, but those are discussed more in detail
|
|
in <a href="package-management-making-packages.html#PACKAGE-MANAGEMENT-MAKEPKG">Section
|
|
18.3.2</a> below.</p>
