When the Debian delta contains multiple pieces which interact,
or which you aren't going to be able to upstream soon,
it might be preferable to
-maintain the delta as a rebasing patch series,
-to facilitate
-reviewing/upstreaming/dropping
-individual pieces.

For such a workflow see for example

=head1 CONVERTING AN EXISTING PACKAGE
This section explains how to convert an existing Debian package to
=head2 Existing git history using another workflow
-First, dump any existing patch queue:
+First, if you don't already have the git history locally, clone it,
+and obtain the corresponding orig.tar from the archive:
+
+=over 4
+
+ % git clone git.debian.org:collab-maint/foo
+ % cd foo
+ % origtargz
+
+=back
+
+Now dump any existing patch queue:
=over 4
=back
+=for dgit-test dpkg-source-ignores begin
+
Now you simply need to ensure that your git HEAD is dgit-compatible,
-i.e., it is exactly what you would get if you ran B<dpkg-buildpackage
--i\.git/ -I.git -S> and then unpacked the resultant source package.
+i.e., it is exactly what you would get if you ran
+B<dpkg-buildpackage -i'(?:^|/)\.git(?:/|$)' -I.git -S>
+and then unpacked the resultant source package.
+
+=for dgit-test dpkg-source-ignores end
To achieve this, you might need to delete
I<debian/source/local-options>. One way to have dgit check your
progress is to run B<dgit build-source>.
-The first dgit push will require I<--overwrite>.
+The first dgit push will require I<--overwrite>. If this is the first
+ever dgit push of the package, consider passing
+I<--deliberately-not-fast-forward> instead of I<--overwrite>. This
+avoids introducing a new origin commit into your git history. (This
+origin commit would represent the most recent non-dgit upload of the
+package, but this should already be represented in your git history.)
