In order to get a SUSE guest running and installing fine i have added a
correct capability for installing rsync and nfs-client.
I have included SUSE naming fixes as well because SUSe doesnt get
spelled SuSE anymore :).
I don't use `activated` here because I'd really like to optimize
performance as much as possible, and loading files from disk is
generally slow. So instead of using `activated` I load the file at the
last possible moment which is when the exact class is being requested.
I don't think many people will do this outside of the core, and I'm not
too concerned.
