To replace one symlink with another atomically is possible by using rename() or
renameat()
something like:
os.symlink( src, tmp_symlink )
os.rename( tmp_symlink, dst )
Use dir_fd's to taste.
I'm sure there is a lot more to cover all the corner cases and attack vectors.
I'm not sure how immutable file will help with this.
