[why] our os-cifs container will mount three dir, /srv/os /srv/initrd /srv/result it's may cause:
- our cifs service becomes slow
- if the container exit, none of the three folders can be accessed.
in order to reduce the coupling, need split them
Here needs a blank line.
[how] one folder mount by one container

Thanks, Xijian
[Usage]: Two ways for the client to mount initrd:
- initrd.
mount -t cifs -o guest,port=446 //ip/initrd /tmp/initrd 2. osimage. mount -t cifs -o guest,port=446 //ip/osimage /tmp/osimage
