Thank Troy and Connie for the `positive' 'negative' answers toward other
solutions instead of reinstallation.
I will do that. Actually before asking those questions, I have already
educated myself that I will do this before Christmas.
One thing that makes me really sorry for doing this is that there had
been many people in this mailing list
encourging me to use x86_64 Linux instead of i386 Linux.
