It's quite obvious what the corresponding code is doing, and it isn't
any harder to understand than the rest of the code that's not commented.

This is a quick sanity check with 'podman images' to ensure that all the
images are in place before running 'list'. Other tests already do this,
so this change makes these two tests consistent with the rest.
https://github.com/containers/toolbox/pull/1273
This is the 'simple' case of having a well-known Toolbx image (ie.,
not a copy, not an image without a name, not a non-Toolbx image). It's
good to ensure that the default image works as expected with 'list'
before moving on to more complex scenarios.

Currently, some of the names of the tests were too long, and had
inconsistent and verbose wording. This made it difficult to look at
them and get a gist of all the scenarios being tested. The names are
like headings. They shouldn't be too long, should capture the primary
objective of the test and be consistent in their wording.

Toolbx was conceived to address the needs of Fedora Linux. Even though
it works on host operating systems outside the Fedora family, it hasn't
treated them with the same importance as Fedora Linux and derivatives
like Red Hat Enterprise Linux. Subsequent commits will change that by
adding first-class support for host operating systems beyond the Fedora
universe. eg., Arch Linux and Ubuntu.
The current Toolbx maintainers, Ondřej Míchal and myself, are Fedora
developers and don't have the bandwidth to drive changes and track down
bugs in OSes outside the Fedora family. Therefore, maintenance of some
parts of the code base will be delegated to contributors from those
other OS communities.
This is a step in that direction by clearly specifying which part of the
code base is maintained by whom.

This uses 'skopeo inspect' to get the size of the image on the registry,
which is usually less than the size of the image in a local
containers/storage image store after download (eg., 'podman images'),
because they are kept compressed on the registry. Skopeo >= 1.10.0 is
needed to retrieve the sizes [1].
However, this doesn't add a hard dependency on Skopeo to accommodate
size-constrained operating systems like Fedora CoreOS. If skopeo(1) is
missing or too old, then the size of the image won't be shown, but
everything else would continue to work as before.

Bind mounting the locations at runtime doesn't really have anything to
do with whether /run/host/etc is present inside the Toolbx container.
The only possible exception could have been /etc/machine-id, but it
isn't, because the bind mount is only performed if the source at
/run/host/etc/machine-id is present.
This is a historical mistake that has persisted for a long time, since,
in practice, /run/host/etc will almost always exist inside the Toolbx
container. It's time to finally correct it.

The --monitor-host option was added to the 'init-container' command in
commit 8b84b5e460 to accommodate Podman versions older than 1.2.0
that didn't have the '--dns none' and '--no-hosts' options for
'podman create'. These options are necessary to keep the Toolbx
container's /etc/resolv.conf and /etc/hosts files synchronized with
those of the host.
Note that Podman 1.2.0 was already available a few months before
commit 8b84b5e460 introduced the --monitor-host option. The
chances of someone using an older Podman back then was already on the
decline, and it's very unlikely that a container created with such a
Podman has survived till this date.
Commit b6b484fa79 raised the minimum required Podman version to
1.4.0, and made the '--dns none' and '--no-hosts' options a hard
requirement. The minimum required Podman version was again raised
recently in commit 8e80dd5db1 to 1.6.4. Therefore, these days,
there's no need to separately use the --monitor-host option of
'init-container' for newly created containers to indicate that the
Podman version wasn't older than 1.2.0.
Given all this, it's time to stop using the --monitor-host option of
'init-container', and assume that it's always set. The option is still
accepted to retain compatibility with existing Toolbx containers.
For containers that were created with the --monitor-host option, a
deprecation notice will be shown as:
$ podman start --attach CONTAINER
Flag --monitor-host has been deprecated, it does nothing
...
https://github.com/containers/toolbox/pull/617
So far the minimum required Podman version was 1.4.0, based on what used
to be available in RHEL 7. These days, Podman 1.6.4 is old enough to be
in RHEL 7.9. Hence it's time to bump the baseline.

This is meant to roughly replicate the build environments used by
downstream distributors to build toolbox(1). These can be restricted in
odd ways compared to a fully featured environment where toolbox(1) is
actually going to be used. eg., the inability to use podman(1) in the
case of Fedora or not having subordinate user and group ID ranges in the
case of openSUSE.
It's important to ensure that toolbox(1) can be built by downstream
distributors without any unnecessary hassle.

Ever since commit bafbbe81c9, the shell completions are generated
while building Toolbx using the 'completion' command. This involves
running toolbox(1) itself, and hence validating the subordinate user and
group ID ranges.
Unfortunately, some build environments, like openSUSE's, don't have
subordinate ID ranges set up. Therefore, it's better to not validate
the subordinate ID ranges when generating the shell completions, since
they are generated by Cobra itself and subordinate ID ranges are not
involved at all.
Note that subordinate ID ranges may be needed when the generated shell
completions are actually used in interactive command line environments.
The shell completions invoke the hidden '__complete' command to get the
results that are presented to the user, and, if needed, the subordinate
ID ranges will continue to be used by podman(1) as part of that.

Having a separate convenience function reduces the indentation levels by
at least one, and sometimes two, and makes it easy to have more detailed
debug logs.
This will make the subsequent commit easier to read.

Ever since commit bafbbe81c9, the shell completions are generated
while building Toolbx using the 'completion' command. This involves
running toolbox(1) itself, and hence invoking 'podman version' to decide
if 'podman system migrate' is needed or not.
Unfortunately, some build environments, like Fedora's, are set up inside
a chroot(2) or systemd-nspawn(1) or similar, where 'podman version' may
not work because it does various things with namespaces(7) and clone(2)
that can, under certain circumstances, encounter an EPERM.
Therefore, it's better to avoid using podman(1) when generating the
shell completions, especially, since they are generated by Cobra itself
and podman(1) is not involved at all.
Note that podman(1) is needed when the generated shell completions are
actually used in interactive command line environments. The shell
completions invoke the hidden '__complete' command to get the results
that are presented to the user, and, if needed, 'podman system migrate'
will continue to be run as part of that.
This partially reverts commit f3e005d014
because podman(1) is now only an optional runtime dependency for the
system tests.

It's better not to use the global flag variables beyond the top-level
RunE functions, because sometimes the lower-level functions are re-used
from other files within the 'cmd' package. In this case,
createContainer(), and hence pullImage(), is also used in src/cmd/run.go
to implement the 'run' command. However, the 'run' command doesn't have
a --authflags option.
Since the default value of the flag is the zero value of the type, which
is a NOP in the code, it's likely that the code was still correct, but
it will be better to maintain some discipline here to highlight the
inputs needed by the lower-level functions. Otherwise, things can get
tangled up.
