The hardlinks were to libraries in /usr/lib from somewhere else or vice
versa I cannot remember precisely which.. Took out OpenOffice which was
an unpleasant surprise at the time... I cannot remember precisely which
libraries were involved but as usual for these things I discovered the
problem when I needed to use OpenOffice in a hurry. It only took 10 to
15 minutes to diagnose and fix but it was a bloody nuisance at the time.
I not entirely certain whether there are not any other broken links
created by this move, but I will probably find out the hard way *sigh*

Next time I do this I will make sure that I check for such linkages
before I move structures to new partitions...:-)
