1.5.3. Installing Signed Packages
Installation for most packages can be done safely (except kernel packages) by issuing the following command:
rpm -Uvh /tmp/updates/*.rpm
For kernel packages use the following command:
rpm -ivh /tmp/updates/<kernel-package>
Replace <kernel-package> in the previous example with the name of the kernel RPM.
Once the machine has been safely rebooted using the new kernel, the old kernel may be removed using the following command:
rpm -e <old-kernel-package>
Replace <old-kernel-package> in the previous example with the name of the older kernel RPM.
It is not a requirement that the old kernel be removed. The default boot loader, GRUB, allows for multiple kernels to be installed, then chosen from a menu at boot time.
Before installing any security errata, be sure to read any special instructions contained in the errata report and execute them accordingly. Refer to
Section 1.5.4, “Applying the Changes” for general instructions about applying the changes made by an errata update.
