The value of this setting is the number of older kernels that are kept when a new kernel is installed by yum. If the number of installed kernels becomes greater than this, the oldest one gets removed at the same time a new one is installed. This cleaning can also be done manually with a command that belongs to the yum-utils package : `package-cleanup –oldkernels –count=2` |
