| ### Using @sys and @host Variables Follow the suggested conventions in the OSF DCE DFS Administration Guide and Reference when using the @sys and @host variables in certain path names. When the DFS Cache Manager encounters one of these variables, it substitutes a string that consists of the local machine's architecture and operating system type for @sys or the hostname for @host, causing a certain directory to be used. Using @sys and @host is helpful when you are constructing symbolic links from the local disk to DFS. You can create identical symbolic links on all machines, but each machine transparently accesses the files appropriate to its system name or hostname. The DFS cm sysname command sets and displays the current value for @sys.
