Indeed, /boot does not need to be a separate partition. I have /boot 
within the root filesystem on my test boxes where I know I will need to 
install many / all kernels for testing / development purposes for the 
specific reason that I do not need to set a size for /boot and it can 
just consume whatever it needs from the rest of the filesystem.
