Currently, the hash_ops is only used by set, so this does not change
anything. But, there are several benefits,
- we can drop cast in the definition,
- the hash_ops can be also used by hashmap.
We carry a special logic for /usr/ in initrd that it initially gets
mounted to /sysusr/usr/ and later bind mounted to /sysroot/usr/.
When hooking up validatefs it is hence necessary to wait for
the bind mount and validate that, rather than the /sysusr/usr/
established as intermediate transport.

Otherwise, if already 'remove' uevent for the device is queued, then
the device node may not exist any more when 'udevadm wait' command succeeds.

This also makes udevd/udevadm mention that the parent device rules
also tested with the device currently processing.
With the following rules file:
```
ATTRS{idVendor}=="0001", ATTRS{idProduct}=="44ff", MODE="0666", GROUP="input",
```
Before:
```
event0: /tmp/hoge.rules:1 Checking conditions for parent devices: ATTRS{idVendor}=="0001", ATTRS{idProduct}=="44ff"
event0: /tmp/hoge.rules:1 No parent device passed parent conditions.
```
After:
```
event0: /tmp/hoge.rules:1 Checking conditions for parent devices (including self): ATTRS{idVendor}=="0001", ATTRS{idProduct}=="44ff"
event0: /tmp/hoge.rules:1 ATTRS{idVendor}=="0001": Cannot read sysfs attribute: No such file or directory
input0: /tmp/hoge.rules:1 ATTRS{idVendor}=="0001": Cannot read sysfs attribute: No such file or directory
PNP0C0E:00: /tmp/hoge.rules:1 ATTRS{idVendor}=="0001": Cannot read sysfs attribute: No such file or directory
LNXSYBUS:00: /tmp/hoge.rules:1 ATTRS{idVendor}=="0001": Cannot read sysfs attribute: No such file or directory
LNXSYSTM:00: /tmp/hoge.rules:1 ATTRS{idVendor}=="0001": Cannot read sysfs attribute: No such file or directory
event0: /tmp/hoge.rules:1 No parent device passed parent conditions.
```
Prompted by #37063.
Previously, log level, properties, maximum number of worker processes,
and so on set by 'udevadm control' are discarded on restart. This makes
the configuration serialized on stop and deserialized in next
invocation. Also, this introduces 'udevadm control --revert' to clear
previous configurations.
Previously, configurations set by 'udevadm control' such as log level,
maximum number of childrens, global properties, and so on were discarded
on restart. This makes udevd serialize those configurations on stop, and
deserialize them in the next invocation.
Installing symlinks pointing to directories with install_subdir() is
broken (see https://github.com/mesonbuild/meson/pull/14471). Let's work
around the issue for now by manually installing the standalone directory
until the issue is fixed upstream and available in meson in all supported
distributions.
It is useful to have stable and unique identifiers for a security
principal. The majority of identitiy management systems in use with Unix
systems today (e.g. Active Directory objectGUID, FreeIPA ipaUniqueID,
Kanidm UUIDs) assign each account and group a unique UUID and exposing
that to applications allows them to refer to accounts in a stable
manner.
At this time we are merely adding the properties to the user/group
records. Adding ways to perform lookups by these IDs is left for a
future PR.
See [discussion](https://mastodon.social/@pid_eins/114283987142625086) and
[this comment](https://github.com/systemd/systemd/issues/24032#issuecomment-2745246757).
I'm sure there are wording aspects which could be improved, but I
believe this is a reasonable initial stab at the problem.
Let's make sure the mkosi can be built (with `NO_BUILD` enabled) without
the source tree available. This allows running the integration tests
when only distribution packages are available but the source tree is
not.
If the integration tests have been installed in the systemd-tests
package, the path to these in mkosi.postinst.chroot will be wrong.
Let's fix the issue by moving these files into the mkosi/ directory
as they're only used by mkosi regardless so they make more sense to
be there anyway.
Let's rely on tmpfiles to put our nsswitch.conf in place instead of
doing it in the post-install script. This moves us one step closer
to being able to build the mkosi image without having the source
tree available when NO_BUILD is used.
