mount挂载问题

nswcfd

mount [-fnrsvw] [-t vfstype] [-o options] device dir

对于某些文件系统而言，device是什么并不重要，可以随便填，比如proc

mount -t proc any_device_name_you_want_to_use  /proc

不好意思，遗漏了一种情况。楼主的例子里，应该是/etc/fstab里有关于/mnt/test的定义项。

              The mount program does not read the /etc/fstab file if device (or LABEL/UUID) and dir are specified. For example:

                     mount /dev/foo /dir

              If you want to override mount options from /etc/fstab you have to use:

                     mount device|dir -o <options>

              and then the mount options from command line will be appended to the list of options from /etc/fstab.  The usual behaviour is that the last option wins if there is more duplicated options.
