I (incorrectly) assumed that --relinquish-var does everything --flush
does, including moving already existing stuff from /var/log/journal/ to
/run/log/journal/, but that's not the case. To actually do that we need
to shuffle things manually, so let's do just that.
This should make issues like #31334 easier to debug, since with this
patch we now have a coredump in the test journal as well:

This commit adds a new way of forwarding journal messages - forwarding
over a socket.
The socket can be any of AF_INET, AF_INET6, AF_UNIUX or AF_VSOCK.
The address to connect to is retrieved from the "journald.forward_address" credential.
It can also be specified in systemd-journald's unit file with ForwardAddress=
owneridmap bind option will map the target directory owner from inside the
container to the owner of the directory bound from the host filesystem.
This will ensure files and directories created in the container will be owned
by the directory owner of the host filesystem. All other users will remain
unmapped. Files to be written as other users in the container will not be
allowed.
Resolves: #27037
Othewise test images are missing the tmpfiles snippets used to create the very
basic files at boot, which can be useful when a test wants to reuse the OS tree
(is already running in) for spawning a new container in pristine state.
Given that the test involves screen(1), sending various control sequences to
resize/clear the screen, most of the logs sent from the python script were
nearly impossible to read or mixed with other messages sent to the console
hence making the debug harder when the test is run manually.
This patch introduces an option to redirect the pexpect IOs into a file (to be
used in $STATEDIR/TEST-69-SHUTDOWN/run-nspawn).
The pexpect logs are also enabled later so the boot logs are skipped since
those are already included in the journal.
For the other verbs turning off JSON mode makes sense, but for "call"
not so much, after all the contents of a method call reply is JSON we
couldn't really show any other way.
Hence, when JSON output was not configured otherwise in "call", default
to the same as -j.
I think this was just overlooked in #13754, which removed
the restriction of Restart= on Type=oneshot services.
There's no reason to prevent RestartForceExitStatus=
now that Restart= has been allowed.
Closes#31148
When we're running with sanitizers, sd-executor might pull in a
significant chunk of shared libraries on startup, that can cause a lot
of memory pressure and put us in the front when sd-oomd decides to go on
a killing spree. This is exacerbated further on Arch Linux when built
with gcc, as Arch ships unstripped gcc-libs so sd-executor pulls in over
30M of additional shared libs on startup:

The terminate() method sends SIGHUP but this signal is not handled by
systemd-nspawn hence the process just exits leaving the container scope around
breaking futher test executions.
This patch sends SIGTERM instead which is a defined API to request
sytemd-nspawn to stop and release the container's resources properly.
Follow-up for 8a7032cfb1.
... i.e. apply nested config (exclusions and such) when executing R and D.
This fixes a long-standing RFE. The existing logic seems to have been an
accident of implementation. After all, if somebody specifies a config with
'R /foo; x /tmp/bar', then probably the goal is to remove stuff from under /foo,
but keep /tmp/bar. If they just wanted to nuke everything, then would not specify
the second item.
This also makes R and D use O_NOATIME, i.e. the access times of the directories
that are accessed will not be changed by the cleanup.
Obviously, we'll have to add this to NEWS and such.
Looking at the whole tmpfiles.d config in Fedora, this change has no effect.
The test cases are adjusted as appropriate. I also added another test case for
'R'/'D' with a file, just to test this code path more.
Replaces #20641.
Fixes#1633.
