 Bind-mount \fIsrc\fR into the chroot directory at \fIdest\fR, optionally writeable.
 The \fIsrc\fR path must be an absolute path.
+If \fIdest\fR is not specified, it will default to \fIsrc\fR.
 If the destination does not exist, it will be created as a file or directory
 based on the \fIsrc\fR type.
