It's a valid complaint.  The duplication of similar information is bad,
and /etc/mtab is cleaner as a symlink.  I would like to see the additional
information in /etc/mtab put into /proc/mounts too, though I appreciate
it's difficult (since the kernel does not know about these extra bits of
information; it's all handled in userspace by mount/umount).
