rpm -qa

Alternatively, if he's modified config files etc., running "rpm -Va"  
will list changes (it
won't list cases where files have been _added_ without RPM, though)

If stuff has been added without RPM, and haven't then been added in  
clearly separate
locations, it'll get more painful, but you can list all files RPM  
knows about with "rpm -qla",
which would give a reasonable starting point to diff against "find /"  
to see what files have
been added to the system.

I've used the above before to reconstruct installation instructions  
for various servers
that was a hodgepodge of  manually installed stuff before, and it's no  
fun but it works.
Especially if there's a reason backup to bail you out when there's  
something you've
forgotten to copy over...
