How-To refresh the kernel source tree or kernel-source package

1. YAST-based removal and reinstallation of kernel sources:
	a. Launch YAST
	b. search "kernel-source"
	c. if YAST indicates 'I' the package is already installed on the
           machine.
	d. Using space bar change the option 'I' to '-' and proceed, this
           will	uninstall the package.
	e. repeat steps (a)-(b).
	f. Now using space bar select the option 'I' against the
           kernel-source package.
	g. Accept the changes and proceed. The package should be installed
           if there were no error messages.
	
2. Command-line-based removal and reinstallation of kernel sources:
	a. The rpm file has been copied to /usr/ksource on most of the
           machines. If it is not on your machine, log onto other machines
           and look for it.  When you find a copy, use the "hostname -i"
           command to discover the IP address of that host.  Then copy the
           rpm to your machine with the secure shell copy command such as:
                scp a.b.c.d:/usr/ksource /usr/ksource
           Where "a.b.c.d" is the host IP indicated by the
           "hostname -i" command. 
	b. Check to see if the package is already installed with the
           command:
		rpm -q kernel-source
	c. If the package is installed, uninstall it with:
		rpm -e kernel-source
	d. Verify that the package is un-installed using step (b).
	e. Install the package with:
		rpm -i /usr/ksource/k*.rpm (or the file location)
	f. Verify that the package is installed using step (b).
