It removes the currently running kernel from the list of
kernels to pick as potential candidates for removal, and iterates through
the remaining installed kernels removing the oldest, until it
reaches the maximum of whatever tokeep is set to
in /etc/yum/pluginconf.d/installonlyn.conf
because its first action is to ignore the currently running kernel,
there's always a safe kernel to boot back into.
