Robert... how you doin?? :-)
 
Any symlinks vs regular links to deal with?
Just because /u was no longer mounted would not remove the real
data on the /u partition... nor free up the space occupied by the
/u mounted partition weither the data was removed or not.
I personally like having a /u partition even if only one HD.
