Oh, one other thing I probably should clarify about this, that might
not be immediately evident to others, is that this isn't actually a
problem that gitpkg *requires* you to have.  In the case you hit,
it was purely a function of the workflow that the person who created
that repo chose to use.

You could quite equally use a workflow where you do commit your
patch series (so that the checked out tree is in the same as one
you'd see for the other tools), and gitpkg will quite happily
work with that too (and you don't need to enable any hooks to
do it if you go that way).

If you have any repo where you can run dpkg-bp in the working dir
and get a valid package (regardless of how it was created or what
other tools were used to do that), then gitpkg can export a source
package from it, in its default configuration, with no other hooks.

The big difference is gitpkg also gives you the option to use other
alternative workflows too, on a repo by repo basis, depending on
how the various tradeoffs of doing that balance out for you.

Initially, I was rather coy about overspecifying the workflows that
*I* thought were useful in the documentation, partly because there
was no established best practice and it was quite possible that
other people would invent things even better than what I had been
experimenting with at the time, if given a free hand to do that
and minimal prior brainwashing about "how it should work".

That seemed like an opportunity not to waste.  But we may be at
the stage where we could describe a few of the more proven options
in a bit more detail now with less risk to short-circuiting new
and useful innovation.

[this is another one of those things where I'm really too close to
it to easily remember all the things I just take for granted that
aren't necessarily obvious to everyone else (yet), without the
perspective and input of other people :]
