The Debian packaging of our RINA kernel builds with GCC 4.9,
which is not available on Stretch:

  # apt install ./linux-build-deps_4.1.33+rina65.g2e1cdbcb4-1_amd64.deb
  ...
  The following packages have unmet dependencies:
  linux-build-deps : Depends: gcc-4.9 but it is not installable

Now that the test suite passes again for Jessie, let's try Stretch.

that is the latest version supported by ez_setup.py used in bootstrap-buildout.py.

  Upgrade officially all SR to latest zc.buildout version.

- version up: setuptools 30.1.0
- revert commit 1d0a8073

Then we'll upgrade setuptools for everyone at the same time as we switch to
zc.buildout 2.x

While:
  Installing lxml-python.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

Same as for commit fcb6a81d,
but for the build of the 'hellorina' SR inside the VM.

We want it next to eggs/parts/..., not in slapos.git/software/build-rina/

Error: Buildout now includes 'buildout-versions' (and part of the older 'buildout.dumppickedversions').

This is possible because this SR is only supposed to be run by a test node:
in this case, the owner of the software is the same as for the instance.

Buildout 2.x is required for automatic creation of the 'download-cache' folder.

Anyway, the repository contains more than just rina-tools.

This is implement as a test suite so that it can be automatically on any commit
to rina/slapos repositories.

Currently, the Debian packaging of the kernel only supports Debian Jessie.
