QWG Errata components Templates that define latest errata updates – Looks something like this: # Template to add update RPMs to base configuration template rpms/errata/ ; '/software/packages'=pkg_ronly('ImageMagick',' el5_5.2','i386'); '/software/packages'=pkg_ronly('ImageMagick',' el5_5.2','x86_64'); '/software/packages'=pkg_ronly('ImageMagick-c++',' el5_5.2','i386'); '/software/packages'=pkg_ronly('ImageMagick-c++',' el5_5.2','x86_64'); '/software/packages'=pkg_ronly('ImageMagick-c++-devel',' el5_5.2','i386'); '/software/packages'=pkg_ronly('ImageMagick-c++-devel',' el5_5.2','x86_64'); '/software/packages'=pkg_ronly('ImageMagick-devel',' el5_5.2','i386'); '/software/packages'=pkg_ronly('ImageMagick-devel',' el5_5.2','x86_64') ; '/software/packages'=pkg_ronly('ImageMagick-perl',' el5_5.2','x86_64'); '/software/packages'=pkg_ronly('NetworkManager',' el5_5.1','i386'); '/software/packages'=pkg_ronly('NetworkManager',' el5_5.1','x86_64'); '/software/packages'=pkg_ronly('NetworkManager-devel',' el5_5.1','i386'); '/software/packages'=pkg_ronly('NetworkManager-devel',' el5_5.1','x86_64'); '/software/packages'=pkg_ronly('NetworkManager-glib',' el5_5.1','i386'); '/software/packages'=pkg_ronly('NetworkManager-glib',' el5_5.1','x86_64'); '/software/packages'=pkg_ronly('NetworkManager-glib-devel',' el5_5.1','i386'); '/software/packages'=pkg_ronly('NetworkManager-glib-devel',' el5_5.1','x86_64'); '/software/packages'=pkg_ronly('NetworkManager-gnome',' el5_5.1','x86_64');

QWG Errata components Templates that define errata “fixes” – Looks something like this: template rpms/errata/ fix; '/software/packages'= if ( exists('/software/packages/cups') ) { pkg_repl("poppler-utils"," el5_4.11","x86_64"); } else{ SELF; }; '/software/packages'= if ( exists('/software/packages/' + escape('java openjdk')) ) { pkg_repl("tzdata-java","2010l-1.el5","x86_64"); } else{ SELF; }; # To keep puppet happy '/software/packages'= if ( exists('/software/packages/ruby') ) { pkg_repl('ruby',' el5_3.7',PKG_ARCH_DEFAULT); pkg_ronly('ruby-devel',' el5_3.7',PKG_ARCH_DEFAULT); pkg_ronly('ruby-docs',' el5_3.7',PKG_ARCH_DEFAULT); pkg_repl('ruby-libs',' el5_3.7',PKG_ARCH_DEFAULT); pkg_ronly('ruby-mode',' el5_3.7',PKG_ARCH_DEFAULT); pkg_ronly('ruby-tcltk',' el5_3.7',PKG_ARCH_DEFAULT); } else{ SELF; };

QWG Errata components Templates that initialises errata version – Looks something like this: unique template config/os/errata/ init; variable OS_KERNEL_VERSION_ERRATA ?= nlist( 'sl540', ' el5', ); # Because JAVA is updated, define a new DEFAULT version to be configured variable JAVA_JDK_DEFAULT_VERSION ?= "1.6.0_20";

QWG Errata components There are of tools to make generating these easier utils/misc/rpmErrata.pl /www/htdocs/packages/os/sl470-x86_64/errata/ > cfg/os/sl470-x84_64/rpms/errata/ tpl

QWG Errata components Variables that select and control errata used – Three main ones: OS_ERRATA_TEMPLATE This is the default across your site set in site/os/errata-defaults template NODE_OS_ERRATA_TEMPLATE Set in nlist for specific nodes: variable NODE_OS_ERRATA_TEMPLATE = nlist( escape('lcg0614.gridpp.rl.ac.uk'), 'rpms/errata/ ', escape('lcg0616.gridpp.rl.ac.uk'), 'rpms/errata/ ', ); PKG_OS_ERRATA_TEMPLATE_DEFAULT Can be set for cluster, or in machine template (But Michel’s documentations suggests not to use it….

Conclusion Flexible system Easy to use when you get to know it Can pull errata templates from QWG when they come out But if it is urgent you can just create your own
