Hello, Yes, it definitely is. I'll attach a python script we use here, but if you want to write your own, a useful resource is the API docs (which can be found at http://$your_spacewalk/rhn/apidoc/ . Some notes on our script: - it uses the local /etc/yum.conf "exclude" directive to mask packages that will be pushed for updates - inactive or locked systems will not have updates pushed out to them - the script does its best to try to not schedule duplicate updates (it looks at pending events and masks out packages that are currently queued) - there's a commented-out block at the end that can apply errata, too- although it does not currently respect the yum.conf excludes (*note*: without this, updates /with/ errata will not be applied!) Two bugs: - clients will occasionally fail to install updates (although they will be re-queued next run) for one of two reasons: the repodata isn't written out yet that contains the new package information, or they use the yum cache and again don't see the package. In at least one of these cases, I've seen a "success" returned- although, again, the package will get re-queued the next run. - there was a bug (rhbz 588901) in system.listLatestUpgradablePackages that returned too many packages. This should be fixed in sw1.1. Also, as Tomas said, there is a checkbox in the webui as well, but that only applies updates with errata. Hope to help, Josh
