Errata

-                      v5
+                      v6
 When enabled, OS errata deployment will use a template `rpms/errata.tpl` in the templates for the OS version used on a specific node. This default name can be changed using variable `PKG_OS_ERRATA_TEMPLATE` to define the template to use. It is '''strongly recommended''' to use a non default name to avoid any clash with the `errata.tpl` provided by the standard templates. This also allows to produce a different template for a different version of the errata (using the date in the template name for example) with a finer control over what is deployed when on which machine.
+It sometimes happens that one errata RPM causes conflicts or have dependencies difficult to solve in the site context. If this RPM is not used or not critical for the site/node, it is possible to remove it by adding to the errata template something like:
+{{{
+'/software/packages' = pkg_del('myconflictingrpm');
+}}}
+''Note: never try to remove the RPM from the base templates used to configure the OS. First it may break some things when the errata are not deployed. Also one specific RPM is often added by several templates. But the main reason is that these templates are entirely [/wiki/Development/Templates/Generated#OSTemplates generated] from distribution official list. You obtain the same result with the line described above, except its effect is only in the context of these errata.''
