Immediately after hitting send on the previous mail it occurred to me
that dpkg-divert might offer the ideal interface for local admins to
tweak the priority ordering from the defaults.

And indeed: 
# dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen

Does exactly what is required and:

# dpkg-divert --rename --remove /etc/grub.d/20_linux_xen

and undoes things (on Squeeze and Wheezy).

For some reason I had it in my head that dpkg-divert didn't work for
conffiles, but on reflection I can't see any reason why that should be
the case.

In the absence of a change or default ordering this seems like by far
the preferable solution, I shall probably update
http://wiki.debian.org/Xen to reflect this fairly soon.

This info would make a nice addition to README.Debian but otherwise I
reckon this bug can be closed.

Ian.
