Now its virtually impossible.  Complete reinstalls on production systems are just not viable.  We need a working way to upgrade.  I haven't found it yet.

It's not necessary to delete the source every time.  But /usr/src should 
be empty before the initial svn checkout, or there will be files in 
there that are unmanaged and can cause problems.  The Subversion 
instructions mention this.  (Or at least some of them do, we have a fair 
amount of similar sections in different chapters and sections that need 
to be combined.)
