Yes.  You will need to break the clean target in two.

The second "clean" (after the primary "fix the upstream tree" clean) is not
to go around deleting auto-fu stuff.  So now you get a "distclean" and
"clean" targets. Only "distclean" must be run only once to do the auto-fu.

The second clean must rename/remove config.status, and config.cache, only.
This assumes the second, third, etc builds don't go messing with auto-fu. If
they do, you need to always full-clean and re-auto-fu everything.

IMHO, as we are going to be using dpatch for *everything* anyway, the
easiest way to go would be:

1. create build-dir (empty, rm -rf it first)
2. copy source three there, patch, auto-fu, configure and build first version of package
3. rm -rf it, repeat for second version of package (this avoids wasting too
much space during the build).

This is the safest way.  It is also slower, but this doesn't bother me at
all: cyrus is still lightweight compared to certain crap out there anyway
that all arches have to build rather constantly (kde, gnome, mozilla, etc),
and if it makes our maintenance easier, makes it harder for a mishap to
happen to the second build tree and makes it harder for us to not notice a
build fuckup, then I am all for it.

It gets also rather easy to use environment variables to select what to
build.

The second way is to do what you're doing now, but instead of cleaning the
tree, you do this:

1. build as normal (single build)
2. make first set of debs
3. patch-in changes, dh_clean -k
4. build again
5. make new sets of debs

I don't like this much, it is hell to get right re. arch-dep and arch-indep,
for example.
