This assumes that there *is* an /etc/fstab entry.  Sometimes system
administrators will perform ad hoc mounts of devices that aren't
mentioned in /etc/fstab.

For example, consider how xfstests works; it will run mounts commands
mentioning the test and scratch devices which are not mentioned on
/etc/fstab.
