This is the equivalent of RequiresMountsFor=, but adds Wants= instead
of Requires=. It will be useful for example for the autogenerated
systemd-cryptsetup units.

Let's put the section name at the beginning of each sentence. This way we
can avoid awkward constructs like "kernel is looked for in the .linux section".
Also, since the paragraph above says that this is a list of "PE sections", we
can just say "section". In other places, it is often useful to say "PE section"
to avoid ambiguity.
Also fix the off-by-one in the count of sections.
The only reason to recommend this would be if people had multiple commands
with the same name in the search path. This probably was never the best idea,
and it happens rarely anyway. Since the patch that dropped requirement for full
paths was introduced, we have dropped support for unmerged-usr and we're planning
to drop support for split-bin at some point too. Many people effectively have just
one directory in the search path, so there is even less reason to use an absolute
path. So let's recommend just using the command name, which makes the unit file
shorter and nicer to read.
An event loop is not "synchronous". So we shouldn't say that the client must
"synchrounusly poll" if we recommend an event loop. Let's just say it should
poll, and say that "sd_bus_wait()" is blocking, which is clearer and more
correct than "synchronous".
AllowList= and DenyList= filter only DHCPOFFER messages. So, if
RapidCommit= is enabled, then networkd unconditionally accepts a rapid
ACK message even if its sender is filtered out by the lists.
As AllowList=/DenyList= implemented earlier than RapidCommit=, so
enabling RapidCommit= unconditionally by default may break existing
setups that use AllowList=/DenyList=.
Let's disable RapidCommit= by default when AllowList=/DenyList= is
enabled. Still the setting can be enabled by setting explicitly even
AllowList=/DenyList= is also specified.
This footgun should at least be documented, if there's not going
to be a shortcut setting to establish the async `journalctl
--follow` equivalent.

With the introduction of SetDisplay() method in 4885d7490b the Display
property emits a "properties changed" message every time the display is
changed using this method, so mark it appropriately.
Caught by systemd/systemd#30029:
systemd-logind[1366]: Got message type=method_call sender=:1.165 destination=org.freedesktop.login1 path=/org/freedesktop/login1/session/_310 interface=org.freedesktop.login1.Session member=SetDisplay cookie=8 reply_cookie=0 signature=s error-name=n/a error-message=n/a

Follow-up to 4885d7490b.
This seems to work as expected. In the issue, doubts were raised whether it
works fine with daemon-reload/daemon-reexec, and it seems to work fine.
(The property cannot be set via set-property, the dbus property is 'const'.
We could relax this, but that'd be a separate feature.)
Closes#29574.
In systemctl-show we only show current swap if ever swapped or non-zero. This
reduces the noise on swapless systems, that would otherwise always show a swap
value that never has the chance to become non-zero. It further reduces the
noise for services that never swapped.
This is pretty low-level functionality, hence placed in systemd-analyze.
This is useful for working with systemd-cryptenroll --tpm2-device-key=,
as it acquires the SRK without requiring the full tpm2-tss tool set.
We already save it in PEM format, also store it TPM2_PUBLIC format next
to it. This is useful for usage with systemd-cryptenroll's
--tpm2-device-key= switch.
This completes/corrects the documentation for the following fields:
COREDUMP_CGROUP= - doc where wrong, actually covered COREDUMP_PROC_CGROUP=
COREDUMP_CMDLINE= → undocumented so far
COREDUMP_PROC_CGROUP= → docs where there but incorrectly assigned to COREDUMP_CGROUP=
COREDUMP_PROC_AUXV= → undocumented so far
COREDUMP_SESSION= → undocumented so far
Fixes: #29832
