Emilien, debtor looks like an interesting tool, thanks for the link.
As far as tracking upstream branches from local forks and carrying local
patches, we've had good luck with using the git-upstream tool on stack
It allows you to merge in upstream changes on a regular basis and will
automatically drop local changes if there is a matching Change-Id field in
the upstream branch. It also allows you to manually tag specific changes
to drop. We have this setup to run as a regular job and the merge commit
for the changes gets pushed to our internal Gerrit instance for review and
all our normal CI tools run against that so we can gauge the impact of the
