+## The problem
+
+Centos kernels tend to accumulate unless you clean them regularly.
+
+## The solution
+
 There is a setting in `/etc/yum.conf` that does exactly that : `installonly_limit=`. 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`
