To use podman run the tests like this:
DOCKER=podman make test-in-docker
This now builds the welder/lorax-tests image as a separate step from
running the tests.
Running the tests uses the welder/lorax-tests image and mounts the
source directory read-only, copies it into /lorax-test/ and runs the
tests from there.
Make runtime directly into squashfs image. This reduces largely
unreproducible ext4 layer, but requires anaconda's dracut module
modification to properly mount the image.
And in an intermediate version it returns a VectorString object which
isn't serializable by the json or toml modules.
So convert it to a list so that the type is consistent in the sources
code.
Some files are created in non-reproducible way, including including
random data explicitly (/etc/machine-id), timestamps (fontconfig cache,
ldconfig aux-cache, certs cache), or entries in random order (groups,
systemd catalog, package list).
Fix this by either making the files reproducible, or removing them.
By default mkfs.mksdos choose volume id based on current time. If
SOURCE_DATE_EPOCH is set, use that instead.

The previous method worked, but wasn't exactly idiomatic. This is more
correct, and appears to work the same (templates depsolve, version globs
work, multiple repos work).
Note that this does use a private dnf attribute ._goal, but the word is
that this is going to become a public api soon, so yes it is there on
purpose.
Depending on how lorax-composer is run setting up an empty blueprints
directory can fail. So this moves checking/creation until after the
other directories are created and uses make_owned_dir to make sure
ownership is correct.
It needs to be root in order to set the ownership and permissions on the
directories that are under /var/lib/lorax/composer/
Refactor the directory creation into a utility function, and use a umask
of 0o006 to ensure that the parent directories created do not have o+rw
set on them (makedirs behavior is different between Python 3.6 and 3.7
so umask of 0 doesn't work consistently).
Images don't work without these fixes:
* Enable Network Manager.
* Disable cloud-init.
* Add Hyper-V modules into initramfs.
Fixes specific for RHEL:
* Create ifcfg-eth0 required by waagent.
* Install python3 and net-tools required by waagent.
Recommended changes:
* Use recommended kernel boot args.
* Disable kdump.
Since these images can be used to create multiple machines, they should
not have a unique machine-id attached to them. Replace /etc/machine-id
with an empty file so that it will be regenerated at boot time.
If a package is in multiple repos dnf may return more than 1 of them
when using best...glob so we pick the highest NEVRA one and install
that.
