This page is intended to explore the possible use of yum-plugin-priorities in order to help prevent the installation of unwanted rpms from 3rd-party repositories such as dag, dries, etc.

=== Installation ===
== Installation ==
yum --enablerepo=extras install yum-plugin-priorities
yum --enablerepo=extras install yum-plugin-priorities
On SME Server 8.x use (untested!)
(untested!)
yum --enablerepo=extras install yum-priorities
yum --enablerepo=extras install yum-priorities
=== Configuration ===
=== Configuration ===
The installation of yum-plugin-priorities will create '''/etc/yum/pluginconf.d/priorities.conf''' with the following settings
[main]
[main]
enabled = 1
enabled = 1
check_obsoletes = 1
check_obsoletes = 1
These settings tell yum to pay attention to the 'priority' setting for each repo, and to make sure the an 'obsoletes' flag in a low priority repo will not result in the removal of a package from a higher-priority repo.

If you are not running SME Server 7.4, update smeserver-yum
yum update smeserver-yum
==== modify yum template ====
cp the original and add the following to the bottom of the fragment
nano -w /etc/e-smith/templates-custom/etc/yum.smerepos.d/sme-base.repo/20repositories
==== Or Modify /etc/yum.conf/* in sme 7.4 ====
if (exists $props{priority})
{
$OUT .= "priority" . '=' . $props{priority} . "\n";
}
create priority db default
==== DB values ====
Use this script to create DB priority values
#!/bin/bash
#!/bin/bash
do
do
db yum_repositories setprop $REPO priority 10
db yum_repositories setprop $REPO priority 10
#set to 99 for testing when you want to remove priority, or use delprop $REPO
#set to 99 for testing when you want to remove priority

signal-event yum-modify
yum update enablerepo=dag (priority=10)
=== Usage ===
* If you install any contribs or non-sme packages using any form of ''--enablerepo=<xxx>'', update with the following to make sure you get any available updates for your extra packages
yum update --enablerepo=<xxx> --enablerepo=<xxx2>
* If you get a ''missing dependency'' error from yum
** re-run yum manually using ''--exclude <pkgname>'' on the command line, replacing <pkgname> with the package that is preventing your update
** If you suspect that the blocked update resolves a security issue, you must decide for yourself whether to compromise the original SME Server/CentOS package and force the update of the non-SME Server/CentOS package by running
yum update --enablerepo=<xxx> --enablerepo=<xxx2> --noplugins <pkgname>
