cleaning house on radius server?

[Christ Schlacta]

I've got a radius server up and running, and I want to clean up my 
configuration as much as possible.  is it a safe assumption that if I 
remove a file (actually move it out of the way) and attempt to 
authenticate a client that if the client can successfully authenticate 
that everything is working?  is it also safe to assume that any file 
with no uncommented lines is also safe to remove?  I'm most interrested 
in removing the SQL directories and all the unused modules in the 
modules directory.
