我在 Debian 7.7 上进行了以下设置：
me@PiWi$ sudo mount.cifs -o user=me,ro //192.168.1.101/media/Data/Games ./Games
me@PiWi$ ls ./Games/
Afdrukbaar Console Dos ScummVm Windows
me@PiWi$ touch ./Games/Ishouldnbeable
touch: cannot touch `./Games/Ishouldnbeable': Read-only file system
me@PiWi$ ls ./Games/

正如您所看到的，我将 CIFS 安装为 ro，但仍然能够对其进行写入。我尝试使用 noperm 选项，但它没有解决问题。这是怎么回事以及如何解决这个问题...
mount | grep Games
给出以下输出
//192.168.1.101/media/Data/Games on /opt/share/Shared/Games type cifs (ro,relatime,sec=ntlm,unc=\\192.168.1.101\media,username=me,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.1.101,unix,posixpaths,serverino,acl,rsize=1048576,wsize=65536,actimeo=1)
