When certain directories, like /tmp, get mounted over, FCOS/Linux can
act in unexpected ways. Added a sanity check for a list of directories
think might be impacted by this. Also, moved the volume parsing earlier
in the init process so we can catch problems before the expensive
decompression of machine images.
The following destinations are forbidden for volumes:
`/bin`, `/boot`, `/dev`, `/etc`, `/home`, `/proc`, `/root`, `/run`, `/sbin`, `/sys`, `/tmp`, `/usr`, and `/var`. Subdirectories

On Linux systems, the quadlet(5) manpage points to the actual content at
podman-systemd.unit(5) but this cannot be counted on elsewhere. In
particular, this symlink isn't installed by the macOS Brew package, and
https://docs.podman.io/en/latest/markdown/quadlet.5.html is a broken
URL. Symlinks are also unlikely to function properly within the Windows

* there is no way to add a file to an artifact that already exists in

This way has a huge disadvantage: The user will not see an error when he
uses a non-existent option. Another disadvantage is, that if we add more
options within podman, they might collide with the names chosen by
plugins. Such issues might be hard to debug.
The advantage is that the usage is very nice:
--network bridge:opt1=val1,opt2=val2.
Alternatively, we could put this behind `opt=`, which is harder to use,
but would solve all issues above:
--network bridge:opt=opt1=val1,opt=opt2=val2

By default today, the container is always started if its pod is also
started. This prevents to create custom with systemd where containers in
a pod could be started through their `[Install]` section.

disable that behavior.
This prevents the pod service from changing the state of the container

As documented in the issue there is no way to wait for system units from
the user session[1]. This causes problems for rootless quadlet units as
they might be started before the network is fully up. TWhile this was
always the case and thus was never really noticed the main thing that
trigger a bunch of errors was the switch to pasta.
Pasta requires the network to be fully up in order to correctly select
the right "template" interface based on the routes. If it cannot find a
suitable interface it just fails and we cannot start the container
understandingly leading to a lot of frustration from users.
As there is no sign of any movement on the systemd issue we work around
here by using our own user unit that check if the system session
network-online.target it ready.
Now for testing it is a bit complicated. While we do now correctly test
the root and rootless generator since commit ada75c0bb8 the resulting
Wants/After= lines differ between them and there is no logic in the
testfiles themself to say if root/rootless to match specifics. One idea
was to use `assert-key-is-rootless/root` but that seemed like more
duplication for little reason so use a regex and allow both to make it
pass always. To still have some test coverage add a check in the system
test to ask systemd if we did indeed have the right depdendencies where
we can check for exact root/rootless name match.

These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`.
It is also limited to the last five executions and the first 500 characters per execution.
This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record.
- The `--health-log-destination` flag sets the destination of the HealthCheck log.
- `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`)
- `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory.
- `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs.
- The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file.
- A value of `0` indicates an infinite number of attempts in the log file.
- The default value is `5` attempts in the log file.
- The `--health-max-log-size` flag sets the maximum length of the log stored.
- A value of `0` indicates an infinite log length.
- The default value is `500` log characters.

By default wait only waits for the exit of a container, there is really
no way to make it wait for the removal too when the container was
created with --rm. I though I found a clever way in 8a943311db but this
is not working race free. While it works most of the time any other
parallel process might call syncContainer() before the cleanup process
holds the lock until it removes it. As such the wait hack to only update
the state and not sync the exit file did not work so we can drop that.
However the test wants to wait for the removal to happen by the cleanup
process and we can already say --condition=removing to do this but this
will throw an error if the ctr was removed instead of counting this as
success so fix that as well.

In podman-systemd we are intersecting the worlds of containers
and systemd, and I had to stop and think to understand what
`Exec=` does.
I tried to clarify things more here.
I found it especially confusing because the example at the
very top of the file does:
```
Image=quay.io/fedora/fedora
Exec=sleep 10
```
But that only makes sense because the fedora base image
(being generic) doesn't define an `ENTRYPOINT`, just a `CMD`.
But IMO by far the most common usage for podman-systemd
is "app images" which conventionally should use `ENTRYPOINT`
in general. Maybe we should change the default example,
but I'm leaving that for a later followup.
(It perhaps would have been less confusing if this field
had been called `Args=` to make clear it's quite different
in practice from systemd `ExecStart=`)
