<p>Aivanise: /* Contributions */</p> <hr /> <div>'''OS template metadata''' is a set of a few files containing the following information:<br /> <br /> * List of packages that form this [[OS template]]<br /> * Locations of package repositories<br /> * Scripts needed to be executed on various stages of template installation<br /> * Public GPG key(s) needed to check signatures of packages<br /> * Additional OpenVZ-specific packages<br /> <br /> Using OS template metadata and vzpkg tools, an OS template cache can be created.<br /> &lt;noinclude&gt;<br /> ==Internals==<br /> (Incomplete) Based off the centos-4 vztmpl:<br /> <br /> *addons/vzdev is a static list of most commonly used /dev entries. Provides dev package. Uses MAKEDEV.spec<br /> *addons/MAKEDEV-3.3.13-1.3.swsoft is generated from a copy of fedora core 2's MAKEDEV-3.3.13. Uses MAKEDEV.spec which is a customized version to install only the essential devices and depend on vzdev<br /> *dummy-centos-4 is a placeholder for kernel, module-init-tools, modutils, mingetty, kernel-utils, ethtool, and kernel-drm packages. Uses dummy.spec<br /> *default.list, minimal.list, *.list are list of packages for a flavor of the template. Must contain dummy-centos-4, vzdev, and MAKEDEV packages<br /> *config/yum.conf.in template for yum.conf with tokens replaced during build.<br /> *config/install-pre or install-post is executed by cache-os which is executed by vzpkgcache when creating a template cache<br /> *config/update-pre or update-post is executed when updating a template cache<br /> *config/gpgkeys are the keys for the packages to be cached<br /> *config/rpm contains the rpm version<br /> *vztmpl.spec.in is template for the vztmpl package<br /> *make.defs is the common variables for the make process<br /> <br /> Download the vztmpl-centos-4*.src.rpm. Install it. Modify it.<br /> <br /> To generate the OS template metadata rpm run &quot;make rpms&quot; inside the /usr/src/redhat/SOURCES/centos-4 dir. You will need gcc, rpmbuild, and createrepo packages.<br /> <br /> ==Contributions==<br /> * http://www.neonhost.com/openvz/ - Centos 5 rpm and patch for centos 4 template contributed by Chris Turan. See http://forum.openvz.org/index.php?t=msg&amp;&amp;th=5037<br /> * http://krnjevic.com/wp/wp-content/uploads/2008/04/vztmpl-centos-5-2.0-3.i386.rpm - newer Centos 5 template (see also http://krnjevic.com/wp/?p=80)<br /> &lt;/noinclude&gt;<br /> &lt;noinclude&gt;<br /> <br /> == See also ==<br /> * [[OS template]]<br /> * [[OS template cache]]<br /> * [[OS template cache preparation]]<br /> <br /> [[Category: Definitions]]<br /> [[Category: Templates]]<br /> &lt;/noinclude&gt;</div>
