I'm not sure you actually want a constraint that tests for root, what  
you really care about is whether you have tracing privileges, no?
e.g. on Solaris, an ordinary user can have various privs that give  
access to more or less of dtrace:
	http://wikis.sun.com/display/DTrace/Security
(on Mac OS X, you do indeed need to be root for any of these)

it might be best to have four constraints for the different levels of  
privs possible. To construct them, the easiest and most portable way  
would probably be to try and do a [dtrace] operation that requires the  
given privileges level, or if you want to stay independent of the  
[dtrace] implementation, you could [exec] the dtrace(1) tool with an  
action that requires the given priv level.

I sent you the final eval via email on the 15th, 14:09 CEST (ccd to  
mentors), if you did not receive it let me know, I can resend it...

Cheers,

Daniel
