[Pkg-samba-maint] Ubuntu Samba Git/Bzr?

[Brian Campbell]

I know that this isn't quite the right list, but it looks like there
are a lot of overlapping maintainers between Ubuntu and Debian Samba
packaging so I figured I'd ask here.

I'm wondering if there is a Git or Bzr repo somewhere for the Ubuntu
Samba packaging? I notice that Samba 4.1.6 is in Trusty, and seems to
be based closely on the Debian Samba 4.1.x packaging work. However,
when I looked in the Launchpad Bzr repo according to these
instructions: http://packaging.ubuntu.com/html/udd-getting-the-source.html,
I just find an ancient Samba 3.6.6. The Debian Git repo has the Debian
packaging of Samba 4.1.7, but doesn't seem to have any branches for
Ubuntu.

Is there a repo, Git or Bzr, somewhere which has the Ubuntu packaging
branch? I'm building a patched Ubuntu package, and would like to keep
up with the Debian unstable branch, but merge in the Ubuntu packaging
changes and our own local changes. While I could do so by extracting
the debdiff straight from the Ubuntu packages, I figure it would be
easier if there were a repo tracking this, but I can't for the life of
me track it down.
