/opt is 3.8 GB with 3.3 GB free.

I got the size of that partition from a book (can't remember which it
was) when I was installing this second hd.  It gave suggested partition
sizes for each partition and I made each one bigger than what it
suggested, but I used about the same relative percentages for each
partition it suggested.

I like this idea, but is there some compelling reason to move /opt at
all?  Why not just create the /newroot in the /opt partition and do the
rest as suggested?

Thanks for your input on this Terry, but I don't have the moolah for
another hd right now.

Thanks again,
