The plugin provides a command "versionlock" which allows you to view and edit the list of locked packages easily. yum versionlock add <package-wildcard>... Add a versionlock for all of the packages in the rpmdb matching the given wildcards. yum versionlock exclude <package-wildcard>... Add a exclude (within versionlock) for the latest versions of the packages in the available repos. matching the given wildcards. yum ver- sionlock list List the current versionlock entries. yum versionlock delete <entry-wildcard>... Remove any matching versionlock entries. yum versionlock clear Remove all versionlock entries. FILES

See yum-versionlock.conf(5) for more information. /etc/yum/pluginconf.d/versionlock.list The default place to put package version lock information (one package and version per. line). The file takes entries in the follow- ing format EPOCH:NAME-VERSION-RELEASE.ARCH See rpm(8) for more information on custom query formats. If the package does not have an EPOCH the number will default to 0. BUGS
