We're trying to keep the Solaris and Linux administrative interfaces roughly the same, to make it easy for admins to use either one without separate learning curves. Rob Thurlow mentions that Solaris user interface guidelines require that mandatory command line options must be specified as positional parameters rather than by using dash switches. The only reason I used dash switches for all the options was sheer laziness. This commit updates the FedFS ADMIN client tools that are concerned with remote replication management.
