testdata/ is shared by both the unit tests and the integration tests. Hence it
makes sense to place them right under /usr/lib/systemd/tests/ while the tests
themself are located under dedicated sub-directories:
/usr/lib/systemd/tests/
├── integration-tests
├── testdata
└── unit-tests
├── testdata -> ../testdata
However the unit tests implemented as shell scripts (such as
test-fstab-generator.sh) expect to find testdata/ where the scripts are
installed, ie they do something like:
src="$(dirname "$0")/testdata/test-fstab-generator"
This patch installs a symlink in 'unitestsdir' named "testdata" and that points
to whatever value 'testdata_dir' is set.
/usr/lib/systemd/tests may contain more than the unit tests. For example on
SUSE we also install the integration tests there.
Putting the unit tests in a dedicated directory named 'unit-tests' makes the
layout cleaner.
Note that `run-unit-tests.py` has not been moved so we don't need to adjust
(Fedora) packaging and users also don't need to descend into the subdirectory.
The test files are /proc//auxv files copies from various architecutres
signified by the file name suffix.
Those tests are fairly simple, but when we run them on n architectures, we do
~n² cross-arch tests.
The nvme by-id symlink changes to the latest namespace when a new namespace gets
added, for example by connecting multiple NVMe/TCP host controllers via nvme
connect-all.
That is incorrect for persistent device links.
The persistent symbolic device link should continue to point to the same NVMe
namespace throughout the lifetime of the current boot.
Therefore the namespace id needs to be added to the link name.
Fix check for conflicting and duplicate expressions of types that
support alternative patterns.
Fixes: 3ec58d0cd8 ("udev-rules: check for conflicting and duplicate expressions")
For some unknown reasons, the temporary directory created by the test
below is not removed:
```
# Test the case that a valid symlink is in the path.
label = 'valid_symlink-deep'
test_content('f= {} - - - - ' + label, label, user=user, subpath='/deep/1/2', path_cb=valid_symlink)
```
To keep /tmp clean, let's create the global temprary directory.
Log an error when a rule line contains conflicting match expressions, e.g.
NAME=="value", NAME!="value"
Log a warning when a rule line contains duplicate expressions, e.g.
NAME=="value", NAME=="value"
The interface requires services to write to the cgroup file to activate notifications,
but with ProtectControlGroups=yes we make it read-only. Add a writable bind mount.

Let image_install figures the binary paths out itself as not all distributions
ship the mkfs.* tools in the same location. For example openSUSE ships
mksquashfs in /usr/bin/.
When a rules contains several LABEL tokens, the parser used to silently
discard all of them besides the last one without any diagnostics at all.
It's time to break the vow of silence and let the parser issue a warning.
When udevadm verify is invoked without positional arguments, that is,
when no udev rules files are specified, load all rules files from the system
like the udev daemon does, and verify them.
On Debian the test fails because /run is noexec. Simply create the
script in /tmp (and use a BindPath=), as other tests are doing.

This drops all mentions of gnu-efi and its manual build machinery. A
future commit will bring bootloader builds back. A new bootloader meson
option is now used to control whether to build sd-boot and its userspace
tooling.
This changes the PSI window duration we default to for watching memory
pressure events from 1s to 2s. This is because apparently the kernel
will soon disallow window durations other than 2s for unprivileged
processes.
Hence, we'll bump the threshold from 100m to 200ms, and the window from
1s to 2s.
