systemd-path: order all listed paths by their ID alphabetically
Let's add some system to the madness, given we added user-specific dirs
to the end of the list, but they should really be listed together with
the other user-specific ones.
sd-path: don't chop off trailing slash in sd_path apis, when user provided them
This is a minor compat break, but given the slow adoption of the
sd-path.h APIs I think it's one we should take. Basically, the idea is
that if the user provides a suffix path with a trailing slash (thus
encoding in the path that the last element must be a dir), we should
keep it in place, and not suppress it, in order to not willy nilly
reduce the amount of information contained in the path.
Simplifications that do not alter meaning, and do not suppress
information should be fine to apply to a path, but otherwise we really
should be conservative on this.

debug-generator: add a kernel cmdline option to pause the boot process (#35410)
Introduce the `systemd.break=` kernel command line option to allow
stopping the boot process at a certain point and spawn a debug shell.
After exiting this shell, the system will resume booting.
It accepts the following values:
- `pre-udev`: before starting to process kernel uevents (initrd and
host).
- `pre-basic`: before leaving early boot and regular services start
(initrd and host).
- `pre-mount`: before the root filesystem is mounted (initrd).
- `pre-switch-root`: before switching root (initrd).
[RFC] better naming for Azure MANA network devices (#34255)
The Azure MANA folks would like the PCI domain to be suppressed from
naming network interfaces. Let's introduce a somewhat generic way to do
this, without hardcoding anything to Azure.
Specifically: we'll ship a new hwdb entry that sets a new
ID_NET_NAME_INCLUDE_DOMAIN=0 property on relevant MANA devices. Then we
make net_id look for that property, and if it is set we simply suppress
the PCI domain.
(Untested as of now, needs feedback from Azure MANA folks that this
actually works and does what is requested here).

ukify: Fix regression in --no-sign-kernel flag
The man page says that --sign-kernel and --no-sign-kernel "override the
detection of whether to sign the Linux binary", so we should only
autodetect if neither are specified. But as of commit 02eabaffe98c
("ukify: Add a unified interface for signing tools"), we autodetect even
when --no-sign-kernel is passed, which makes the flag useless.
The sign_kernel option is parsed using argparse.BooleanOptionalAction,
which sets it to either True, False, or None. commit 02eabaffe98c
replaced `sign_kernel is None` with `not sign_kernel`. These are not the
same in Python, as the latter accepts False as well as None.
Restore the original check and fix type annotations accordingly.
Fixes: 02eabaffe98c ("ukify: Add a unified interface for signing tools")
analyze: drop conditioning of --no-legend and --json= on specific verbs
First of all, the list of verbs was badly out of date, in particular for
--no-legend. But second if it, I think such minor switches that alter
some detail of the output should not result in failure when the specific
tweak does not apply on some command. It should be fine for scripts and
suchlike to dumbly always pass --no-legend to all invocations of our
tools without having to consider if a specific subtool of ours actually
supports it or not.
- Downgrade log level for bpf not installed or kernel version
being too old to LOG_DEBUG. Otherwise, on kernels older than 6.12
the log becomes quite annoying.
- Always propagate the error and ignore only on caller's side.
The current style is a messy mix.

resolved: if one transaction completes, expect other transactions within candidate to succeed quickly
Fixes #22575, as suggested by poettering in #35514.
Intended as a workaround for some buggy routers, which refuse to send empty
replies. If systemd-resolved starts two DnsTransactions, one for A and one
for AAAA, and the domain in question has no AAAA entry, then the server will
send a reply for A and no reply for AAAA. Correct behavior for the server would
be to send an empty reply for AAAA.
systemd-resolved would previously keep retrying the AAAA transaction, and
eventually timeout the whole query, returning an error to the caller.
Now, if the server replies to one query and not another, we cut short the
timeout and return the partial result. Returning the partial result allows
the rest of the system to keep working. It matches how e.g. glibc libnss_dns
behaves.

serialize: add explicit calls for finishing serialization
These new calls will do three things:
1. in case of FILE* stuff: flush any pending bytes onto the fd, just in
case
2. seal the backing memfd
3. seek back to the beginning.
Note that this adds sealing to serialization: once we serialized fully,
we'll seal the thing off for further modifications, before we pass the
fd over to the target process. This should add a bit of robustness, and
maybe finds a bug or two one day, if we accidentally write to a
serialization that is complete.
Let's use pwrite() to write the contents of the memfd. This has the
benefit of not moving the file offset, which means we don't have to
reset it after at all.
Let's drop support systems lacking memfds, i.e. pre kernel 3.17 systems.
This allows us to drastically simplify the "data fd" concept, so far
that we can remove it entirely.
This replaces acquire_data_fd() with a specialized call to
memfd_new_and_seal(), not that memfds can be the only implementation of
the concept.
