This adds a `default: true` option for all cases where OSTree
information is specified in schemas and allows for the information
to be picked up from the filesystem.
This is a safe operation because when building disk images there is
no known case where having two deployments makes sense. In the case
there ever were a case then the osname, ref, and serial options still
exist and can be used.

Similar to the aleph file created for builds of FCOS based on ostree
commit inputs, this adds an aleph file that contains information about
the initial deployment of data when the disk image was built
A new stage is preferred here as both the org.osbuild.ostree.deploy
and org.osbuild.ostree.deploy.container stages need an aleph file and
use of the aleph file may depend on the project/product. For example,
right now CoreOS is the only project that uses an aleph file, but others
may want it in the future.
And also set stdout=subprocess.PIPE. This will allow for callers to
parse and use the output of the command, but has the side effect of
meaning less gets printed to the screen during run.

This is a feature that was added in rpm-ostree 2023.10 and is needed
for the new transient /etc feature to work. What it does is change the
labeling of /usr/etc to match those of /etc, so that /usr/etc can be used
directly as a bind-mount or an overlay mount when mounted on /etc.
See https://github.com/coreos/rpm-ostree/pull/4640 for details.
`tox` is a standard testing tool for Python projects, this allows you to
test locally with all your installed Python version with the following
command:
`tox -m test -p all`
To run the tests in parallel for all supported Python versions.
To run linters or type analysis:
```
tox -m lint -p all
tox -m type -p all
```
This commit *also* disables the `import-error` warning from `pylint`,
not all Python versions have the system-installed Python libraries
available and they can't be fetched from PyPI.
Some linters have been added and the general order linters run in has
been changed. This allows for quicker test failure when running
`tox -m lint`. As a consequence the `test_pylint` test has been removed
as it's role can now be fulfilled by `tox`.
Other assorted linter fixes due to newer versions:
- use a str.join method (`consider-using-join`)
- fix various (newer) mypy and pylint issues
- comments starting with `#` and no space due to `autopep8`
This also changes our CI to use the new `tox` setup and on top of that
pins the versions of linters used. This might move into separate
requirements.txt files later on to allow for easier updating of those
dependencies.
Add a new class `SubIdsDB` as a database of subordinate Ids, like the
ones in `/etc/subuid` and `/etc/subgid`. Methods to read and write
data from these two files are provided.
Add corresponding unit tests.
This stage takes /usr/lib/passwd and /usr/etc/passwd from an OSTree
checkout, merges them into one file, and store it as /etc/passwd in the
buildroot.
It does the same for /etc/group.
The reason for doing this is that there is an issue with unstable UIDs
and GIDs when creating OSTree commits from scratch. When there is a
package that creates a system user or a system group, it can change the
UID and GID of users and groups that are created later.
This is not a problem in traditional deployments because already created
users and groups never change their UIDs and GIDs, but with OSTree we
recreate the files from scratch and then replace the previous one so it
can actually change.
By copying the files to the build root before doing any other
operations, we can make sure that the UIDs and GIDs of already existing
users and groups won't change.

Add a simple helper method that returns the path for a deployment,
given the sysroot, the osname, the reference or commit and the
deployment serial. Path might not exist.
`
In python 3.6 the value of `__origin__` for typing.List[str] is
typing.List. This then changed to the actual `list` type in later
versions. Accept both versions.
Add the initramfs-args Treefile option that can be used to pass
arguments to drauct via rpm-ostree. NB: the ostree module will
always be automatically be included by rpm-ostree.
When using rpm-ostree compose, a Treefile[1] controls various
aspects of its behaviour. Since rpm-ostree will, at least in
the beginning, be used to post-process and committing the tree
add a helper class to ease the creation of correct Treefiles.
The docstring of the Treefile contains the information in which
phases ('install', 'postprocess', 'commit') the option is used,
as of rpm-ostree commit 1cf0d557ae8059e689b1fed670022727e9842288
Add basic checks for the ostree.Treefile helper. Some of the
tests require rpm-ostree to be installed.
