The integration tests are installed into the image
with the intention that it should be possible to run those tests,
but those tests require the named user testuser
and tar is needed for machined-import
Most of the integration tests have been made to not write to /usr
but some genuinely need to do so.
Because mkosi creates images with a read-only /usr
it is not normally writeable.
By mounting an overlayfs with /usr as the lower dir
and upper and working dirs in /var tests may write to /usr.
This test is for if devices transition from plugged -> dead -> plugged
on boot, but it is normal to see loop devices transition plugged -> dead
on first boot when systemd-repart adds the root partition.
The systemd-analyze integration test also tests chroots.
It builds its chroot by bind-mounting /,
but since /usr might be a separate mountpoint
it should create the chroot with --rbind.
The reference implementation seems to set the 'parameters' field for
method calls to 'null' if nothing is specified on its command line. We
so far only could deal if the parameters field was unset or set to the
empty object. Let's also accept the 'null' type.
It's pulled in by one of the udev rules (63-md-raid-arrays.rules) and it
fails every time, because there's no valid email address in
/etc/mdadm.conf:
[ 5.778153] testsuite-64.sh[403]: mdadm: array /dev/md/mdmirror started.

[ 5.892618] systemd[1]: mdmonitor.service: Failed with result 'exit-code'.
And as we (re)assemble the MD devices multiple times, this gets quite
noisy, especially since we later start hitting the service start rate
limit.
Fedora has the mdmonitor.service patched, so it won't start without
/etc/mdadm.conf being present, but Arch uses the upstream unit which
doesn't have such guard.
Let's just mask the service completely, which replaces all that noise
with one warning:
[ 6.553583] testsuite-64.sh[294]: + udevadm wait --settle ...
[ 6.580700] systemd[1]: sys-devices-virtual-block-md127.device: Failed to enqueue SYSTEMD_WANTS job, ignoring: Unit mdmonitor.service is masked.
The image name is extracted from the image path originally passed in,
i.e. not the contents of the image. And the image UUID is directly
retrieved from the partition table, hence also not from the contents.
Let's hence move the comment to separate out the stuff extract from the
file systems (and thus only available when mounting/with privs/with
block devices) from the data available without any of that.
This is the common case in --user instances, hence handle this
gracefully.
This should be safe since user instances won't get access to
/dev/console-related ttys anyway, but only their own ptys.
The original version would yield a slightly _unexpected_ message for
this [Address] section:
[Address]
Address=10.9.3.1/24
HomeAddress=yes
ManageTemporaryAddress=yes
systemd-networkd[68396]: /run/systemd/network/25-address-static.network: unexpected address flags "n/a" were configured. Ignoring [Address] section from line 144.
Let's instead show the unexpected flags:
systemd-networkd[69160]: /run/systemd/network/25-address-static.network: unexpected address flags "home-address,manage-temporary-address" were configured. Ignoring [Address] section from line 144.
Currently, start/stop messages for device units are not used, since
job_perform_on_unit() does nothing and we simply wait for unit status
change. I think we still want some nice log messages explaining what
the start jobs for devices are doing, so let's fix this.
Just use ExecParam directly, as these are all internal to sd-exec now
anyway. Avoids double close when execution fails after FDs are set up
for inheritance and were already re-arranged.
