Which is really sad because there's no reason for this.

Proper way to update the link is:

create new link under some unique name,
rename new link so it occupies the old name.

[This will automatically delete the old link if it occupies
the old name.]

I suppose I ought to file a bug report against update-alternatives,
but I don't really have the time at the moment...
