triggers could be used too  (to rm -fr the directory installed by old versions of the package)

Another *be careful* warning for this one too.

A directory (empty or not) can't be automatically replaced by anything 
else (symlink or otherwise) in the existing rpm versions. If absolutely 
necessary, it can be accomplished by doing the necessary renames and 
symlinks in "%pretrans -p <lua>" scriptlet, but that should be only seen 
as the last resort as its not exactly a safe operation.
