Of course, to contain unbounded mount creation, we mark the mount at /user as unbindable.

当然，为了包含非绑定挂载，我们将 /user 下面的挂载标为不可绑定的。

One other specialized mount object is called an unbindable mount, which is like a private mount but also disallows bind mounting itself.

另一种特殊的挂载对象称为不可绑定的挂载(unbindable mount)，它们与私有挂载相似，但是不允许执行绑定挂载。
