Executable Maps A map can be marked as executable. The init script that parses the auto.master map will pass this as a .B program map to the automounter. A .B program map will be called as a script with the key as an argument. This is implemented in the initialization script. A executable map can return an errorcode to indicate the failure in addition to no output at all.
All output sent to stderr is logged into the system logs.
