The -f option to ln was not portable, traditionally. So the portable way to create a symlink if the target might exist is to remove the old symlink first. I've verified that 'ln -sf' indeed works as reported on Solaris 9. On Solaris 10, it seems Sun has finally "given in" and changed the implementation (but not the documentation). I'm not sure why we bother checking whether the old file exists before removing it, instead of just doing 'rm -f'; that has been there since r6352 with no explanation given.
