Hi. Especially for automated nagios/icinga checks it's nice if one could differ between critical and non-critical upgrades in SL repos. This is what the yum security plugin should do but this doesn't work apparently: # /usr/bin/yum check-update -C Loaded plugins: changelog, downloadonly, fastestmirror, keys, priorities, protectbase, ps, security, verify 96 packages excluded due to repository priority protections 0 packages excluded due to repository protections kernel.x86_64 2.6.32-220.17.1.el6 sl-security kernel-devel.x86_64 2.6.32-220.17.1.el6 sl-security kernel-doc.noarch 2.6.32-220.17.1.el6 sl-security kernel-firmware.noarch 2.6.32-220.17.1.el6 sl-security kernel-headers.x86_64 2.6.32-220.17.1.el6 sl-security But the invocation of claims that ne security updates would be avialable # /usr/bin/yum --security check-update -C Loaded plugins: changelog, downloadonly, fastestmirror, keys, priorities, protectbase, ps, security, verify 96 packages excluded due to repository priority protections 0 packages excluded due to repository protections Limiting package lists to security relevant ones No packages needed for security; 5 packages available Any ideas? Cheers, Chris.
