Isar requires a number of extra packages compared to a Yocto build. It
also needs a newer e2fsprogs version which can be taken from backports.
Last but not least, its keystone multistrap contains a nasty bug [1]
under in jessie so that we need to pull the updated version from
stretch.
The value of having this image still based on jessie is that it can be
used for both purposes: Yocto (2.1/2.2) and Isar builds. We push it
along the kas core image as kas-isar during the CI run.
Isar still requires some raised privileges. Therefore, the image has to
be started with the additional switches "--cap-add=SYS_ADMIN
--cap-add=MKNOD --device $(/sbin/losetup -f)".

/usr/share/locale/locale.alias is a symlink to /etc/locale.alias and
needed by locale-gen. /usr/share/locale/locale.alias gets normally
installed by locale package but is filtered in jessie-slim, so re-add
the symlink.

With Sphinx it is possible to create the command line documentation
automatically if there is a function that returns just the command line

Currently the creation of the argument parser is rather entangled with

Changing even simple settings like target or machine requires the
creation of additional configuration files. This does not scale well.
This patch allows the target, machine and distro to be overwritten by
environment variables (called KAS_TARGET, KAS_MACHINE and KAS_DISTRO
respectively).
It also fixes how the environment variables for the proxy settings are
handled. Currently the settings in the config files overwrite the proxy
settings from the environment, but since that would be inconsistent this
patch switches that around. With this patch the environment overwrites
the proxy settings in the configuration file.

If the configuration file structure changes over time, it might
introduce incompatibilities.
This patch introduces versioning of configuration file.
Configuration files needs to add a 'version' entry into their 'header'
like this:
header:
version: '0.9'
After loading this file, the version is checked agains kas version.
Every version 'M.m.p' of kas is allowed to load configuration files with
version 'M.m' and all versions backwards up to and including
the '__compatible_version__' from kas/__version__.py
Signed-off-by: Claudius Heine <ch@denx.de>
In the current configuration file we mix between entries that are file
specific (like includes and later version) and entries that are used by
the rest of kas, that are not file specific (machine, target, repos,
etc.) It might not be obvious to differenciate between those entries.
This patch introduces a header section into the configuration file, to
contain every setting that is specific to the file and not the complete kas
configuration. The 'includes' statement is moved there, because its file
specific.

Splitting configuration files into multiple files and implementing an
include mechanism allows to handle configurations more flexible and
allowing following scenarios:
- including kas configuration file from external meta layer into
own project
- splitting many different similar configurations into multiple files
with only a couple of common files
To include file its necessary to add a 'includes' entry into the kas
configuration. To include files from the same repo, do it like this:
-----
includes:
- ../base/base_include.yml
-----
The path is relative to the current configuration file. If they start
with a path seperator ("/") they are absolute.
To include files from a different repository, do it like this:
-----
includes:
- file: bsps/my_machine_include.yml
repo: collected_machines
repos:
collected_machines:
url: https://url.to.git.repo/
revspec: master
-----
You have to make sure that the repository definition is available
in your current file, or in any include that is available at this
point.
Yaml ("*.yml") and Json ("*.json") files are supported.
Included in this patch are also some changes to the configuration
file structure. Here is an overview:
The value of the 'repos' key is a dictionary that maps a repo identifier
to a dictionary that contains 5 entries:
- url: The url to the repository. If that is missing, no git operations
are used
- refspec: The git refspec of the repository that is used. If that is
missing the latest commit of the default branch is used.
- name: The is defines under which name the repository is stored. If
that is missing the repository identifier is used
- path: The path where the repository is stored. If no url is given and
a path is missing, the repository is referencing the repository under
which the configuration file is stored. If no url is given and a path is
specified, the repository is referencing a directory where layers might
be stored. If an url is specified, path can be used to overwrite the
default (kas_work_dir + repo.name) checkout directory.
- layers: This contains a dictionary of layers, that should be included
into the bblayers.conf. The keys are paths relative to the repository
and the values can be used to exclude layers if they are one of
"excluded", "disabled", "false", "0", "n", or "no". Also boolean values
are accepted. Any other value, including "None" means that this layer is
included into the bblayers.conf. If "layers" is missing or empty, the
repository itself is included into the bblayers. If this is specified, the
repository itself is not included into the bblayers.conf.
