1 - Is it possible to set cvsup for thos operation?

I believe that there are a sup-file for only the kernel sources, however 
if you want to upgrade an application you'll have to upgrade the whole 
world too. Depending on how old your kernel sources are you might need a 
new world to be able to use the new kernel too, I'm not sure about that.

However, if you already have quite recent sources on your computer than 
using cvsup will be quite efficient even if you download both world and 
kernel, since it only download that which has changed.

As for learning about cvsup, there really is not much to it. Take a look 
in /usr/share/examples/cvsup, there you'll find a couple of different 
sup-files ready for use that will download different things (you can 
open them with an editor if you want). Then, when you have found one 
that suits your needs, you run
#cvsup -h <host> /path/to/sup-file
To find a host near you take a look at www.dragonflybsd.org in the 
download section.

If you don't have any recent sources you might want to download a 
snapshot of the sources (find a mirror in the download section) and 
extract that on your computer and then run cvsup to update them to the 
very latest.

More information can be found in the cvsup manual page (man cvsup):
