The problem is that with the "= YES" bit, if you accidently leave the 
variable out of rc.conf (like I did), NO is assumed.  With the "!= NO" 
bit, you get the program run by default and have to specifically 
disable it.

I think it's pretty rare that a machine wouldn't run inetd, and even 
rarer that it wouldn't run cron.
