Okay. They also integrate with git in different ways: dgit calls git
commands here and on alioth, while git-deb is essentially a git plugin.
Aside from the unusual url, it's just another remote in a standard git
repo.

I've mentioned in this thread that the fast-import stream is stable.
It is derived from changelogs and dsc signatures. That makes the top
hash of an import stable.
Matching dgit repos will have to come through graft points; I'm not
going to shed useful metadata or freeze the stream format. The benefit
would be dubious since a shallow stream would never match anyway.

Here's what it looks like:
Permission denied (publickey).
ssh: failed command: ssh coccia.debian.org 'set -e; cd
/srv/ftp-master.debian.org/ftp/dists; if test -h unstable; then readlink
unstable; exit 0; fi; if test -d unstable; then echo unstable; exit 0;
fi; exit 1'
dgit: subprocess failed with error exit status 255
