In reality there are three classes of systems: * pets * cattle * betsy[0][1] The problem is that configuration management systems think everything is either cattle or pets. [0] Betsy is a special cow. She will also be slaughtered, so she is not a pet, but she needs to be taken care of in a special way, so she is not a cattle. [1] When the herd becomes large, you get joahna. joahna is like betsy, but not exactly like betsy so she needs a care and feeding slightly different than the betsys.
