In the context of a table, both would be generally understood to have the same
meaning. "n/a" is a strange beast. It was useful when tables were produced on
the typewriter with "---------" used to separate rows. It is visually more
pleasing to use "-", and there is no risk of it being mistaken for a row
separator.
We have free_and_replace() and friends, they are all named with lower
letters, even they are macros, not functions.
For consistency, let's rename CLOSE_AND_REPLACE() with lower letters.
Seeding RNG via SMBIOS is bad idea, since often measurement of SMBIOS
tables is used for TPM policies, under the assumption SMBIOS remains
static after a certain point.
uid-range: tie up number and array of uid range entries
This renames UidRange -> UidRangeEntry, and reintroduces UidRange which
contains the array of UidRangeEntry and its size.
No fucntional changes, just refactoring.
The array of uid range entries are already sorted. Hence, if x and y are
does not have intersection, then the remaining entries neither have
intersection with x.
The setting ProtectClock= implies DeviceAllow=, which is not suitable
for udevd. Although we are slowly removing cgropsv1 support, but
DeviceAllow= with cgroupsv1 is necessarily racy, and reloading PID1
during the early boot process may cause issues like #24668.
Let's disable ProtectClock= for udevd. And, if necessary, let's
explicitly drop CAP_SYS_TIME and CAP_WAKE_ALARM (and possibly others)
by using CapabilityBoundingSet= later.
units: make sure that initrd-switch-root.service pulls in .target
Normally we queue initrd-switch-root.target/isolate, which pulls in the
service via Wants= in the .target unit file. But if the service is instead
started directly, there may be nothing pulling in the target. Let's make
sure that the reference exists.
units: add dependency ordering for emergency.service conflicts
If we want to stop those services which would compete for access to
the console, we need to have an ordering so that they are actually
stopped before the other things starts, not asynchronously.
units: add ordering dependencies on initrd-switch-root.target
For shutdown, we queue shutdown.target/start, so in every unit which should be
stopped *before* shutdown, we need both Conflicts and an ordering dependency
with shutdown.target (either Before= or After= would work, because stop jobs
are always ordered before start jobs).
For initrd transition, we queue initrd-switch-root.service/isolate. This
automatically creates a /stop job for every running unit without
IgnoreOnIsolate. But no ordering dependency is created, unless the unit has a
(possibly transitive) ordering dependency on initrd-switch-root.service.
Since most units must stop before the transition, we should add the ordering
dependency. It is nicer to use Before=initrd-switch-root.target for this.
initrd-switch-root.target is ordered before initrd-switch-root.service, so
the effect it the same when both are in a transaction.
Fixes #23745.
To also cover the case where somebody is emergency mode in the initrd and
queues initrd-switch-root.service/start (not isolate), also add
Conflicts=initrd-switch-root.target, so various units are stopped properly.
This extends 2525682565b372b9b83c848bfe89c025fed47a1d to cover all the other
services that are touched. It could be consider "operator error", but it's
easy to make and it's nicer if we can make this more foolproof.
The block is reordered and split to have:
1. description + documentation
2. (optionally) conditions
3. all the dependencies
I think it's easier to read the units this way.
Also, the Conflicts+Before is seperated out to separate lines.
The ordering dependency is "fake", because it could just as well be
After=, we are adding it to force ordering wrt. shutdown.target, and
it plays a different role than the other Before=, which are about a
real ordering on boot.

pstore: do not try to load all known pstore modules
Commit 70e74a5997 ("pstore: Run after modules are loaded") added After=
and Wants= entries for all known kernel modules providing a pstore.
While adding these dependencies on systems where one of the modules is
not present, or not configured, should not have a real affect on the
system, it can produce annoying error messages in the kernel log. E.g.
"mtd device must be supplied (device name is empty)" when the mtdpstore
module is not configured correctly.
Since dependencies cannot be removed with drop-ins, if a distro wants to
remove some of these modules from systemd-pstore.service, they need to
patch units/systemd-pstore.service.in. On the other hand, if they want
to append to the dependencies this can be done by shipping a drop-in.
Since the original intent of the previous commit was to fix [1], which
only requires the efi_pstore module, remove all other kernel module
dependencies from systemd-pstore.service, and let distros ship drop-ins
to add dependencies if needed.
Since LGTM is no longer enabled for the systemd repo (as it's going to
be discontinued by the EOY), let's run CodeQL on every PR instead to
replace it.

xdg-autostart-service: Use common boolean parser
Technically the desktop entry specification says value should be the
string "true" or "false". Pragmatically every desktop has their own
parsing rules which are typically less strict on how to interpret other
values.
This caused some regressions downstream when we switched to the
xdg-autostart-generator where existing handmade files contained values
with "True" or "False".

hwdb: Fix Acer Aspire One AOD270/Packard Bell Dot keymappings
The Acer Aspire One AOD270 and the same hardware rebranded as
Packard Bell Dot SC need a couple of keymap fixups:
1. The switch-video-mode key does not do anything. Standard acer-wmi
maps scancode 0x61 to KEY_IGNORE since typically these events are
duplicate with the ACPI video bus. But on these models the ACPI video
bus does not send events for this key, so map it.
2. The Brightness up / down hotkeys send atkbd scancode 0xce / 0xef
which by default are mapped to KEY_KPPLUSMINUS and KEY_MACRO.
These actually are duplicate events with the ACPI video bus,
so map these to KEY_IGNORE.
