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 :).
When using pty=true, removing files using sudo may request confirmation,
which will hang the connection.
Similarly, sometimes assumptions about file existence may be wrong and
in those cases it seems better to continue on as long as the file does
not exist, so -f makes sense there, too.
