Well, sorta. With Windows or OSX or whatever you can get a list of all 
the updates it wants to install and you can check/uncheck them 
individually, and you can download a lot of the major 
updates/KBs/service packs separately and install them offline if you 
need to. I was hoping there was something similar for FreeBSD.
