df reports from the device what space is available and what is used. du
examines the filesystem. When another filesystem is mounted on a
mountpoint, the portion of the original filesystem below the mount point
is concealed by the newly mounted filesystem. The two utilities are
answering different questions.
Because of the different ways they work, du cannot answer the question
"How much space is left?" and df cannot answer the question "How much of
the used space is visible in the filesystem?"
