Hi Antonis -

In the standard universe, system calls are intercepted via a library 
linked into the job via the condor_compile tool, and are then performed 
remotely upon the submit machine.

In the vanilla universe, no libraries are linked into the job binary and 
thus no system calls are intercepted.  Thus system calls for an 
executable submitted into the vanilla universe are handled directly by 
libc and/or the kernel on the execute machine (aka worker node).

regards,
Todd
