A mount namespace is a tree of mount points. In addition, mounts have another type of dependencies which is called groups. Each mount can be a member of two groups, it can be a slave in one group and a member of another group. Currently groups can’t be set, it can be only inherited from a source mount. It is always a problem when more than one type of properties have to restored for one call. This means that we have to find a sequence of steps to get a required state.

In case of mount namespaces, one more problem is over-mounts. A few mounts may be over-mounted or processes can have file descriptors which are linked with over-mounted files.
