 // relies heavily on the GetNode method as a way of directing
 // system calls that take a path as an argument.  The methods
 // of this class are pure virtual.  BaseMount class contains
 // stub implementations for these methods.  Feel free to use
 // BaseMount if your mount does not implement all of these
 // operations.
