  The old libraries will only be linked by programs that do not use them.
  I fail to see how that is useful.

What is useful is that programs that were compiled under older versions
of the system on the same machine will continue to work, instead of the
user being hosed and having to have a flag day rebuild of all sorts of
programst that they might not even know depend on krb5.  For example, I
could no longer print.  Fortunately I was able to figure it out nearly
instantly because I understand this stuff.

Why is it so important to nuke the old libraries, breaking programs
compiled against them?
