  • BehobenRed Hat Enterprise Linux AS (Advanced Server) version 2.1

    Before applying this update, make sure all previously released errata relevant to your system have been applied. To use Red Hat Network to upgrade the kernel, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. Note that you need to select the kernel explicitly if you are using the default configuration of up2date. To install kernel packages manually, use "rpm -ivh <package>" and modify system settings to boot the kernel you have installed. To do this, edit /boot/grub/grub.conf and change the default entry to "default=0" (or, if you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and run lilo) Do not use "rpm -Uvh" as that will remove your running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.
