After convincing Kay Sievers, I am going to push this patch, as it fixes
obviously non-predictable symlinks.
To fix already released systemd versions, I would suggest to patch them in a
way, that it outputs both symlinks and add a release note, that the old
symlinks are deprecated.
In the long run, we really should outsource all specialized storage udev helper
code, as Kay mentioned in the various replies to this thread.
