I'd second that, with this qualification:

As kernel updates become available, the user will eventually build a 
list of kernels to boot into. I always keep three: the current kernel 
and that last /two/ known good ones. Anything beyond that just fills up 
space in your /boot partition, unless you're a tester or kernel module 
developer. But anything /less/ than that puts you at some non-starter risk.
