Before you set this to a higher value, which is generally a good idea, 
you should first check how large your /boot partition is and work out 
how many you have space for. If /boot is just a directory in / then OK, 
but often /boot is a small partition on its own, and thus will only be 
able to accommodate a certain number of kernels...
