cfengine ideology question

[Lev Lvovsky]

One of our administrators up and left from work recently, so it's 
getting even more important that we get something like cfengine up and 
running (the process has been sidelined by many other things sadly).

I realize that cfagent can execute scripts on a box, but from an 
ideology perspective, is this a bad idea?  One of the main reasons that 
we would use cfagent is to run scripts at designated times, or 
depending on certain circumstances (software release etc...) - is it 
generally done so that you use the functionality of cfagent/cfengine to 
run stuff with its own built-ins, or are external scripts just as 
welcome in its use?

thanks,
