I would rather that they just used the netbios name.  This is also meant
to be unique, and avoids yet another parameter being passed down. 

But regardless of that, it makes me worry - is it not possible to setup
Fedora DS without it modifying /etc/sysconfig?  In environments like
'make test', I really, really want never to run a root, and never to
touch a central system configuration file.  

That is, all evidence of a 'make test' must go away after rm -rf st.
