udev: re-introduce symlinks for loopback block device
But the directories are changed from /dev/loop/by-ref/ -> /dev/disk/by-loop-ref/
and /dev/loop/by-inode/ -> /dev/disk/by-loop-inode/.
As /dev/loop/ is used by losetup command for other purpose.

tree-wide: drop _pure_ + _const_ from local, static functions
This is supposed to be a help for compilers to apply optimizations on
functions where they can't determine whether they are const/pure on
their own. For static, local functions the compiler can do this on its
own easily however, hence the decoration with pure/const is just noise.
Let's drop it, and let the compiler to its thing better.
(Use it for exported functions, since compilers can't 'reach-over' into
other modules to determine if they are pure, except if LTO is used)
sysusers: move global variables into a Context object
Our coding style says static variables suck except for very special
cases, i.e. things like the log level or very per-process stuff, such as
parsed version of cmdline args and such. sysusers departed from that as
one of the very few exceptions in our codebases: it keeps its
operational state in global variables.
Address that. Introduce a Context object that carries the fields that so
far have been global, and pass it around as needed.
This has the nice effect that state and configuration is clearly
separated in code, and we can very clearly see which functions mangle
state and which ones do not.
bootctl: don't advertise systemd-efi-options in --help/man anymore
The command is deprecated, as per NEWS of 254. Let's go one step further
and remove it from the help text and man page, so that people are not
inspired to use it at this time anymore.
This is how we usually have done this before: remove it from visibility,
but support it for a while still.

fstab-generator: update cache in fstab_enabled_full() based on the parsed result of fstab=

fstab-util: introduce fstab_enabled() helper function
And refuse to parse fstab when 'fstab=no' is specified in the kernel
command line.
When 'fstab=no' is specified in the kernel command line, fstab-generator
does not parse fstab and will not create e.g. /boot or /efi mount entry
even if fstab contains entries for the mount points. However, gpt-auto
generator may parse fstab file, and adjust or ignore mounts for EFI or
XBOOTLDR partitions based on the fstab file.
This makes gpt-auto also ignore fstab entries if 'fstab=no' is set in
the kernel command line.
The commit b42482af904ae0b94a6e4501ec595448f0ba1c06 dropped
'--exclude-prefix=/dev' from systemd-tmpfiles-setup.service. So, the
possibly later invocation of the service changes the permission set by
udevd.
As commmented in the head of this file, settings should be consistent
with udev rules. Only missing entry here is vfio. Let's re-add the
entry for the device.
The commit makes systemd-tmpfiles-setup.service also updates the
permission or owner of device nodes. However, the service does not have
ordering for systemd-udevd.service. So, the service may set different
permission from the one udevd already set.

units/initrd-parse-etc.service: Conflict with emergency.target
If emergency.target is started while initrd-parse-etc.service/start is queued,
the initrd-parse-etc job did not get canceled. In parallel to the emergency
units, it eventually runs the service, which starts initrd-cleanup.service,
which in turn isolates initrd-switch-root.target. This stops the emergency
units and effectively starts the initrd boot process again, which likely
fails again like the initial attempt. The system is thus stuck in an endless
loop, never really reaching emergency.target.
With this conflict added, starting emergency.target automatically cancels
initrd-parse-etc.service/start, avoiding the loop.

zsh: reintroduce pattern argument to uncached verbs
The systemctl completion previously made use of PREFIX as a pattern
argument to list-unit-files and list-units. This had the problem of
erroneously filtering the results that were stored in the cache, and
erroneously filtering results that might have been requested according
to the users configuration (e.g. _correct completer, certain
matcher-lists or tag-orders, etc.).
Unfortunately, the runtime of list-unit-files increases when no pattern
argument is provided, and systemctl show, used to filter those units,
can become unacceptably slow when provided with too many units to
describe.
Let's re-introduce the pattern argument to list-unit-files and
list-units where necessary in order to alleviate these bottlenecks
without poisining the cache. A 'use-pattern' style is introduced that
may be used to disable this behavior if it is undesired. We can still
expect that certain completions, like `systemctl start <TAB>` will be
slow, like before. To fix this we will need systemd to learn a more
efficient way of filtering the units than parsing systemctl show.

repart: Extend check for read-only verity partitions
Let's check for verity signature partitions as well. Let's also
check the configured verity mode, which is another way to indicate
verity partitions aside from the type UUID.
Like the cmdline file we look for a devicetree file in
$KERNEL_INSTALL_CONF_ROOT, /etc/kernel and /usr/lib/kernel. If it is
present we look for the specified device tree that comes with the kernel
we're adding and install it into $ENTRY_DIR_ABS and add a devicetree
stanza to the loader entry.
Unfortunately it seems there is no common consensus on where to install
device tree blobs, so we have to look in a few different places for it.
This macros wraps the call to daemon-reexec in all user managers. It would be
called for example from systemd %post right after the call to systemctl
daemon-reexec.
This will be used in the Fedora systemd package to fix a long-standing FIXME.
Tested via building and reinstalling the systemd package with the patches.
Enqueues restart jobs for all units that have the 'needs-restart'
mark, and reload jobs for units that have the 'needs-reload' mark.
When a unit marked for reload does not support reload, restart will
be queued.
The new macros allow a reload to be issued instead of a restart.
Based on the discussion on fedora-devel:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/IJSUGIEJNYZZRE53FF4YFUEBRHRAVIXR/
Tested using dummy package https://github.com/keszybz/rpm-test-reload.
manager: fix reloading in reload-or-restart --marked
bus_unit_queue_job_one has two callers:
- bus_unit_queue_job which would do the appropriate transormations
to turn JOB_TRY_RESTART into JOB_TRY_RELOAD,
- and method_enqueue_marked_jobs which did not.
In effect, method_enqueue_marked_jobs() would queue restart jobs for
units which has Markers= needs-reload or needs-restart.
When the chunk of code which does the transformations is moved from
bus_unit_queue_job to bus_unit_queue_job_one, there is no change for
bus_unit_queue_job, and method_enqueue_marked_jobs is fixed.
The additional checks that are done seem reasonable to do from
method_enqueue_marked_jobs: we shouldn't be restarting units which are
configured to not allow that, or force unwanted start of dbus-broker.
60-ukify.install would only work with initrd provided by command line
arguements. Fixed to look for both microcode and initrd is found in
$KERNEL_INSTALL_STAGING_AREA which is placed by initrd generator like
