 Don't log in twice for "sim sync". This is necessary only to create the
 sourcebasedir if it does not yet exist, which is necessary only very
 rarely. Instead, try rsync directly, and if it fails, examine the error
 message and create the directory if necessary.

 This makes simfactory much nicer to use when one cannot setup an ssh
 agent, i.e. when one has to type in the password or use a token eavery
 time.
