我们为 Domino 的执行程序、数据（除了客户机的邮件数据库外）和 Domino 的地址薄（Names.nsf）都在单个卷（磁盘）上分配了单独的文件系统。
There is a separate z/FS file system allocated on single volume (disk) for the Domino execution, data (excepting client mail databases), and the Domino Directory (Names.nsf).
因而，不常更改的文件系统(例如可执行程序的目录)应以只读方式挂载，避免在系统崩溃后浪费时间来检查这样的系统。
Therefore, filesystems that seldom changed (such as a directory of executable programs) could be mounted read-only so as to not waste time for checking it after a system crash.
然而，如果在一个合法的suid可执行程序与一个人人可写的目录在同一个文件系统中，因此使用nosuid选项来挂载的，那么sui d位就会被忽略，这个可执行程序也就无法正确执行。
However, if a legitimate suid executable is on the same file system as a world writable directory and is thus mounted nosuid, the suid bits are ignored and the executable will not operate correctly.
