Right, but it's a consequence of the way the pools work; when a binary
of the same version in breezy is moved to universe, it moves in the pool
which is shared between hoary and breezy, and one of them has to get a
symlink to fix it up. Changing that would involve some fairly
fundamental modifications to the archive maintenance software.

Those were both consequences of the person who migrated those forgetting
to run the script that fixes up the symlinks afterwards. James was away
most of yesterday, and I didn't know whether I could safely run the
script in question; I do now. James has fixed both xpdf and readahead.

There is a high degree of automation in our archive maintenance, but,
like most things, it isn't perfect. main<->universe migration still has
a manual component.
