Include this repository in your package manager??™s configuration
file, or use YaST to get it. This will simplify the installation process.
CAUTION
Always back up data before manually compiling a new kernel. You never know what can
happen when you are essentially upgrading your OS.
After your new kernel is installed, reboot your system to load the new kernel.
NOTE
When you use YaST to install a new kernel (whether you??™re doing it yourself or YOU is
getting a security patch), YaST will warn you about running the lilo bootloader before
rebooting. It is safe to ignore this warning if you are using grub, the default
openSUSE bootloader.
Kernel Versions
In the preceding section, I mentioned the kernel-of-the-day repository. The very existence
of this place gives you a sense of the pace of development of the kernel. As new features
are added, bugs are fixed, and new technology is incorporated into the code base; new
iterations of the kernel are coming out all the time.
This is the reason why kernel version numbers are so complicated. With most applications,
versioning is a relatively simple operation, with a major version number indicating
lots of new features (or, in the case of commercial applications, at least enough to justify
paying for an upgrade), and one or two digits after the dot indicating bug fix updates.
