Comment 1 for bug 1497275

As per Dmitry B., here's more info:

* paths to git projects (http or ssh) and branches to use:

All packages are stored at:
git clone git://anonscm.debian.org/openstack/FOO.git

Branches are always the default one when cloning, except for a list which is described here:
http://anonscm.debian.org/cgit/openstack/openstack-pkg-tools.git/tree/etc/pkgos/packages-list?h=debian/liberty

For example, if a package is listed at http://anonscm.debian.org/cgit/openstack/openstack-pkg-tools.git/tree/etc/pkgos/packages-list/openstack-release-branch?h=debian/liberty, then we should use the debian/liberty branch.

If a pakcage is listed in http://anonscm.debian.org/cgit/openstack/openstack-pkg-tools.git/tree/etc/pkgos/packages-list/experimental-branch?h=debian/liberty then we should use the debian/experimental branch.

if a package is listed at: http://anonscm.debian.org/cgit/openstack/openstack-pkg-tools.git/tree/etc/pkgos/packages-list/pkg-javascript-repo?h=debian/liberty then we should clone it from git://anonscm.debian.org/git/pkg-javascript/FOO.git

On top of all packages within the PKG OpenStack Alioth group, there's those which I just backport from Sid. Those are listed at in here: http://liberty-jessie.pkgs.mirantis.com/debian/dists/jessie-liberty-backports-nochange/main/source/Sources though this is a list of needed backports for Jessie, there may be a little bit more things to backport for Trusty (like python-netaddr, python-requests and such).

* build target distro:
Currently Trusty, though it would be nice to also have Jessie

If you have more question, let me know.
