IIRC, FSSTND also mandates that no program actually refers directly to
files in /usr/share/.  What shall we do about programs already
internally using /usr/share/ upstream ?

He's not the only one.  I was hit by this with 2 packages, which ended
in `rm -rf's in preinst script to turn around this.  I sent a simple
test-case in a bug-report, and got positive feedback from Ian or Klee
(don't remember), telling they were already investigating this

I'd add that both replacing a plain dir with a symlink, and replacing
a symlink with a plain dir cause problems to dpkg 1.4.0.x.  Never
tried 1.4.1.x.  You've been warned ;)
