It just feels wrong in so many ways.

Why is /boot its own partition and not swap? I suspend to swap, so swap 
has to be as accessible as /boot?

Am I going to enlarge swap at some point using LVM tools? Or shrink it? 
Can you even do that with a swap partition in LVM? So what ARE the 
values of swap in LVM? One less partition, I would think if you are 
going duo boot. But if not, again, where is the beef?
