That looks suspicious:  here it is:
=======================================================================
#disklabel wd1s1

type: EDSI
disk: wd1s1

======================================================================

Now, I only set up 4 partitions (/, swap, /usr, /u) which look to
correspond to a,b,e & f above.  Where on earth c came from is beyond
me.  Any ideas of what is happening (& why & how to fix)?  Thanks 
for the time.
