This is not true - on every rehat system since 8.0 I've been doing this.
No machine had reduced funtionality because of it. In fact, the opposite
happened. Try for yourselves, then tell me.

You are right - but it's working anyway, even with the 'wrong' order, on
my systems. But just setting the path is something I would not call a
'security issue' - any script kiddie knows where to find these programs
even when the path is not available - in fact, most of their 'cake
recipes' use full path :-)
