The only cons I see is that it can be more "difficult" with some
language to gather the real path, but do we really need it? There is
also little time where the symlink doesn't exist, this is when it needs
to be removed before being recreated to point to the new log file. If
your external script try to reopen the log file at this moment it will
complain that file doesn't exists and looping until the file exists is
probably a bad idea.
