This is needed so that we can do different things depending on the
given layout; this will be used in tests for now only. Only GPT
allows for arbitrary number of partitions and once we assert this
in code we will need to adjust the tests accordingly.
NB: This method might be removed again in the future, once generic
LVM support is added everywhere and the ability to differentiate
between MBR and GPT layouts is not needed anymore.
Do not rely on `distro.imageOptions` having any size information,
i.e. `Size` being `0`. Instead use `imageType.Size()` and the
information in the blueprint customization to calculate the size.
This makes the individual distro definitions idenpendent of the
API entry points that currently calculate the size, e.g.:
internal/cloudapi/v1/v1.go:PostCompose line 184
internal/cloudapi/v2/v2.go:PostCompose line 197
internal/kojiapi/server.go:PostCompose line 135
internal/weldr/api.go:composeHandler line 2289
Clean up some implementation aspects of the Fedora distro definition:
- Do not have default Fedora distro version and use `fedora` as the
package name in all places that use it, instead of `fedora33`.
- Fix bugs when wrong (Fedora 33) values were returned by `OSTreeRef()`
and `Releasever()` for newer Fedora releases.
- Test Fedora 35 in package unit tests.
- Add unit test for `OSTreeRef()` method.
- Use architecture name constants from `distro` package, instead of
string literals.

The QEMU assembler in Fedora distro definition for UEFI systems used
longer than allowed label for the VFAT filesystem of the EFI System
Partition. The maximum allowed label length is 11 characters.
This worked before with dosfstools, but in 2018, they added a label
validation [1]. This change got into the v4.2 release of dosfstools,
released in Jan 2021. And subsequently since F34, this new version of
dosfstools is present in Fedora repositories.

Each image type now implements BuildPipelines(), which returns a list of
pipeline names that set up the build environment, and
PayloadPipelines(), which returns a list of pipeline names that create
the OS image (all non-build pipeline names).
Older distros that produce v1 manifests should call the distro Fallback
functions to return the common defaults.
A Fallback function for the Exports() method is also added and called by
older distros.
All image types that produce v2 manifests (distros after RHEL 8.4)
should include the information in the image type definition and should
not rely on fallbacks for default values.

The problem: osbuild-composer used to have a rather uncomplete logic for
selecting client certificates and keys while fetching data from
repositories that use the "subscription model". In this scenario, every
repo requires the user to use a client-side TLS certificate. The problem
is that every repo can use its own CA and require a different pair of
a certificate and a key. This case wasn't handled at all in composer.
Furthermore, osbuild-composer can use remote workers which complicates
things even more.
Assumptions: The problem outlined above is hard to solve in the general
case, but Red Hat Subscription Manager places certain limitations on how
subscriptions might be used. For example, a subscription must be tight to
a host system, so there is no way to use such a repository in osbuild-composer
without it being available on the host system as well.
Also, if a user wishes to use a certain repository in osbuild-composer it
must be available on both hosts: the composer and the worker. It will come
with different pair of a client certificate and a key but otherwise, its
configuration remains the same.
The solution: Expect all the subscriptions to be registered in the
/etc/yum.repos.d/redhat.repo file. Read the mapping of URLs to certificates
and keys from there and use it. Don't change the manifest format and let
osbuild guess the appropriate subscription to use.
composer doesn't support f34 or f35, but it should be possible to build
these even with the f33 distro definition. Introduce f34 and f35 repos
and aliases for f33.
Composer does not have 1:1 mapping of what can be the Host Distro name
and the names of supported distributions held in the Distroregistry.
The fact that the host distro `Name()` method as passed to the Weldr API
does not return the same name as what is used as distro name for
repository definitions. This makes it hard to use `distro.Distro` and
`distro.Arch` directly and rely on the values returned by them as their
name.
Add `New*HostDistro()` to all distro definitions, accepting the name
that should be returned by the distro's `Name()` method. This is useful
mainly if the host distro is Beta or Stream variant of the distro.
Change the distroregistry.Registry to contain host distro as a separate
value set when creating it using `New()` function. This value is
returned by `Registry.FromHost()` method. Determining the host distro is
handled by the `NewDefault()` function. Move the distro name mangling to
distroregistry package. Add relevant unit tests.

imageTypeS2 implements the distro.ImageType interface buts generates a
Manifest matching the new osbuild v2 schema.
Two new image types are added to the rhel84 distro (x84_64 and aarch64)
for generating OCI containers contain an Edge (ostree) commit and, when
run, start a web serer to serve the commit.
The image type uses the new PackageSets map to define packages (and
excludes) for the image. The old methods (Packages() and
BuildPackages()) are implemented for compatibility with the old
workflow.
The image also defines an extra package set for the container that will
serve the package: "httpd" (and its dependencies).
The distro.ImageType interface has a new method: Exports()
It should return a list of names or IDs of artefacts that should be
exported from osbuild when the job is complete.
For the old image types, this is simply set to "assembler".
The same test is run in distro/distro_test.go. The redundancy was probably
caused by a bitrot in several commits.
I decided to remove the test from distro implementations to reduce the amount
of duplicated code.

This replaces Packages() and BuildPackages() by returning a map of
package sets, the semantics of which is up to the distro to define.
They are meant to be depsolved and the result returned back as a
map to Manifest(), with the same keys.
No functional change.

Explicitly set the kernel to boot into.
Also change the blueprint/kernenl handling:
Rather than only falling back to the default kernel name for
getting the package list, let GetKernel() always return the
correct result so we can rely on this being consistent.

Rather than setting this automagically, expose it to the caller. For
now the only caller we have simply passes it back in, so this is a
noop.
In follow-up commits this will be used to resolve the parent commit.
This is tested by verifying that the generated manifests do not
change.

The kernel now comes from the blueprint packages even when it's not
specified. Removing from the base packages of the image types avoids
duplication and allows for alternative kernels to be specified without
also including the default.
The latter is necessary for RHEL for Edge and Fedora IoT images (ostree
commits) that fail to build when multiple kernels are installed.
ImageType tests modified to fix expected package order.
Test for each distro that runs through all architecture - image type
combinations and calls the Manifest() method with a kernel boot option
customization and checks if the ostree image types produce the expected
error.
Kernel boot parameters have no effect on ostree type images (Fedora IoT
and RHEL for Edge). Catch this and fail early in the pipeline creation
and communicate the issue to the user.
Imagine this situation: You have a RHEL system booted from an image produced
by osbuild-composer. On this system, you want to use osbuild-composer to
create another image of RHEL.
However, there's currently something funny with partitions:
All RHEL images built by osbuild-composer contain a root xfs partition. The
interesting bit is that they all share the same xfs partition UUID. This might
sound like a good thing for reproducibility but it has a quirk.
The issue appears when osbuild runs the qemu assembler: it needs to mount all
partitions of the future image to copy the OS tree into it.
Imagine that osbuild-composer is running on a system booted from an imaged
produced by osbuild-composer. This means that its root xfs partition has this
uuid:
efe8afea-c0a8-45dc-8e6e-499279f6fa5d
When osbuild-composer builds an image on this system, it runs osbuild that
runs the qemu assembler at some point. As I said previously, it will mount
all partitions of the future image. That means that it will also try to
mount the root xfs partition with this uuid:
efe8afea-c0a8-45dc-8e6e-499279f6fa5d
Do you remember this one? Yeah, it's the same one as before. However, the xfs
kernel driver doesn't like that. It contains a global table[1] of all xfs
partitions that forbids to mount 2 xfs partitions with the same uuid.
I mean... uuids are meant to be unique, right?
This commit changes the way we build RHEL 8.4 images: Each one now has a
unique uuid. It's now literally a unique universally unique identifier. haha

Attempt to clarify the structure of our tests. Each test case is now
encapsulated in a script in `test/cases`. Each of these scripts should
be runnable on a pristine machine and be independent of each other. It
is up to the test-orchestractor to decide if they should be run
consequtively instance, or in parallel on separate instances. Each
script can execute several tests and call whatever helper binaries
is desired. However, each case should be assumed to always run as one.
No tests should be run directly from git, but should rather be installed
onto the test system using rpm and run from there. This moves towards
unifying our two types of test cases.
The new structure of is now:
`test/cmd`: the executors, one for each test-case. This is installed
into `/usr/libexec/test/osbuild-composer`.
`test/data`: data and config used by the tests. This is installed into
`/usr/share/tests/osbuild-composer`.
`schutzbot`: configuration of the actual test run. In particular, this
is where the distros and repositories to test against are
configured.
This is very much still work-in-progress, and is only the first step
towards simplifying schutzbot. Apart from moving files around, this
should be a noop.

Fedora 33 images can now be built and test cases are added for the new
images. The fedora 33 qcow2 and vmdk images are based off of the
official images and their kickstarters found here:
https://pagure.io/fedora-kickstarts. The fedora 33 iot image is based
off of the the config found here: https://pagure.io/fedora-iot/ostree.
The openstack, azure, and amazon image types have changes made to them
based off of the changes made to the qcow2. The changes between fedora
32 and fedora 33 are as follows:
Grub now loads its kernel command line options from
etc/kernel/cmdline, /usr/lib/kernel/cmdline, and /proc/cmdline instead
of from grub env. This is addressed by adding kernelCmdlineStageOptions
to use osbuild's kernel-cmdline stage to set these options. Alongside
`ro biosdevname=0 net.ifnames=0`, we also set `no_timer_check
console=tty1 console=ttyS0,115200n8` per what is set in the official
qcow2. For azure and amazon, the kernelOptions are still set as they
were in fedora 32.
The timezone is now set to UTC if a user does not set a timezone in the
blueprint customizations. Also, the hostname is set to
localhost.localdomain if the hostname isn't set in the blueprint.
Finally, the following packages have been removed:
polkit
geolite2-city
geolite2-country
zram-generator-defaults
