Fine, publish_cds only replaces what's in there already, so I can
either remove that code, or make it so that the replacement is also
relative.  I still need publish CDs to move the images from the
staging area to the published area, and generate the MD5SUMS files,
but it would become pretty trivial if it didn't have to do the

The nice thing about setting it at publish time is that you can run
publish_cds with a version number of "pre-release-test" say, and if it
works, re-run it with "3.X_rY" on the same images, with no oportunity
to screw up. ;-)

Not that I do that sort of test, now that publish_cds works.

Oh the other thing that you may not have noticed is that I have a
hacked up version of publish_cds, called build_snapshot, that I run on
raff to build the matching snapshot for us.cdimage.d.o.

Since the bulk of fallback requests go to raff, I don't see the nasty
hack going away too soon I'm afraid :-/

I should tidy build_snapshot up, take the funcionality out of
publish_cds, and put build_snapshot into CVS really, so others can
build snapshots (although I'm not sure how useful that is, given that
there are only two places that the jigdos point at)

Cheers, Phil.
