[why] our os-cifs container will mount three dir, /srv/os /srv/initrd /srv/result it's may cause: 1. our cifs service becomes slow 2. if the container exit, none of the three folders can be accessed. in order to reduce the coupling, need split them [how] one folder mount by one container [Usage]: Two ways for the client to mount initrd: 1. 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
