I'm adamant on minimal hardware. Once installed it's hard to get 
rid of. And in this case is detrimental to understanding basics.

If I follow a guide that assumes the installation of DHCP, when I 
run into problems it will be simpler to ask assistance of those 
who have used that guide. {Notice I said "when" not "if" ;}

assumes a mindset.

The "what" is trivial. The "how" is not the first time.

I already had the information in the body of that page.
*HOWEVER* there is a massive amount of context in three of the 
items in the left column. *_THANK YOU_* for those links.
