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 )
Somebody can replace tmp_symlink between os.symlink() and os.rename().
Not if tmp_symlink is created in a directory with strict permissions, I
guess.
But in such case we do not need complex games with a temporary symlink.
Just use os.symlink() and os.unlink() if needed.
I was talking about the *tmp_symlink*, not *dst*.
They both should be on the same file system. The simplest way to achieve
this is to create tmp_symlink in the same directory as dst.
