According to Brantley Coile, the Cisco PIX firewall had a xyzzy command that simply said "Nothing happens." He also put the command into the Coraid VSX to escape the CLI and get into the shell. It would announce "Foof! You are in a directory. There are files here." The new California Coraid management, made development to change the string to "/exportmode" and get rid of the "Foof!" message Since regaining ownership of the Coraid software, the command is being returned to the system and now, in VSX release 8, the response is "Â»Foof!Â« You are in a debris room.".
