hwdb: Update GP-electronic T701 accel mount settings (#7220)
The GP-electronic T701 has its LCD panel mounted upside-down, initially
my plan was to fix this by transparently rotating the image in the i915
driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but
that approach has been rejected instead the kernel will now export
a "panel orientation" property on the drm-connector for the panel and
let userspace deal with it.
Since the upside-down-ness of the panel is now no longer transparently
hidden from userspace, the current accel mount quirk for the T701 needs
to be updated to take the upside-down-ness into account.

hwdb: add a hwdb file to override ID_INPUT assignments
The input_id builtin assigns the various ID_INPUT based on the exported evdev
bits. In some cases, the device may not have the properties required to label
a device as one specific type but the physical form factor is clear.
e.g. in the case of #7197 it's a tablet pad that does not have x/y axes which
the kernel exports for pads for historical reasons.
A custom override is needed, best to be solved with a hwdb entry.

journalctl: add --output-fields= (#7181)
This option allows restricting the shown fields in the output modes that
would normally show all fields. It allows clients that are only
interested in a subset of the fields to access those more efficiently.
Also, it makes the resulting size of the output more predictable.
It has no effect on the various `short` output modes, because those
already only show a subset of the fields.
core: add support for expanding state/cache/log directory root in unit files
This augments %t which already resolves to the runtime directory root, and
should be useful for units that want to pass any of these paths in
command line arguments.
Example:
ExecStart=/usr/bin/mydaemon --datadir=%S/mydaemon
Why not expose a specifier resolving directly to the configured
state/runtime/cache/log dir? Three reasons:
1. Specifiers should be independent of configuration of the unit itself,
and StateDirectory= and friends are unit configuration. See 03fc9c723cfc59467a7fccc305f34273f8564b25 and related work.
2. We permit multiple StateDirectory= values per unit, and it hence
wouldn't be clear which one is passed.
3. We already have %t for the runtime directory root, and we should
continue with the same scheme.

nspawn: EROFS for chowning mount points is not fatal (#7122)
This fixes --read-only with --private-users. mkdir_userns_p may return
-EROFS if either mkdir or lchown fails; lchown failing is fine as the
mount point will just be overmounted, and if mkdir fails then the
following mount() will also fail (with ENOENT).
After previous output from systemd-shutdown indicated a bug, my attention
was drawn to redundant output lines. Did they indicate an anomaly?
It turns out to be an expected, harmless result of the current code. But
we don't have much justification to run such redundant operations. Let's
remove the confusing redundant message.
We can stop trying to remount a directory read-only once its mount entry
has successfully been changed to "ro". We can simply let the kernel keep
track of this for us. I don't bother to try and avoid re-parsing the
mountinfo. I appreciate snappy shutdowns, but this code is already
intricate and buggy enough (see issue 7131).
(Disclaimer: At least for the moment, you can't _rely_ on always seeing
suspicious output from systemd-shutdown. By default, you can expect the
kernel to truncate the log output of systemd-shutdown. Ick ick ick!
Because /dev/kmsg is rate-limited by default. Normally it prints a message
"X lines supressed", but we tend to shut down before the timer expires
in this case).
I also tested with `systemctl reboot --force`, plus a loopback mount to
cause one of the umounts to fail initially. In this case another 2 lines
of output are removed (out of a larger number of lines).
core: in --user mode, report READY=1 as soon as basic.target is reached (#7102)
When a user logs in, systemd-pam will wait for the user manager instance to
report readiness. We don't need to wait for all the jobs to finish, it
is enough if the basic startup is done and the user manager is responsive.
systemd --user will now send out a READY=1 notification when either of two
conditions becomes true:
- basic.target/start job is gone,
- the initial transaction is done.

The assumption was that nothing changes in the final attempt. This
would be confusing if a filesystem with a process in uninterruptible

up and don't try to e.g. unmount any parent mounts.
I don't know how possible that is. But the code will be easier to read

When using strftime in arbitrary locales, we cannot really say how big the
buffer should be. Let's make the buffer "large", which will work fine pretty
much always, and just print n/a if the timestamp does not fit. strftime returns

units: replace remote-cryptsetup-pre.target with remote-fs-pre.target
remote-cryptsetup-pre.target was designed as an active unit (that pulls in
network-online.target), the opposite of remote-fs-pre.target (a passive unit,
with individual provider services ordering itself before it and pulling it in,
for example iscsi.service and nfs-client.target).
To make remote-cryptsetup-pre.target really work, those services should be
ordered before it too. But this would require updates to all those services,
not just changes from systemd side.
But the requirements for remote-fs-pre.target and remote-cryptset-pre.target
are fairly similar (e.g. iscsi devices can certainly be used for both), so
let's reuse remote-fs-pre.target also for remote cryptsetup units. This loses
a bit of flexibility, but does away with the requirement for various provider
services to know about remote-cryptsetup-pre.target.

shared: add vectorized parse_field() (#7056)
By vectorizing parse_field() the chain of parse_field() calls in

While at it, eliminate the repeated strlen() calls performed on constant
field names by making parse_field() receive the field length, and storing
it in the ParseFieldVec at compile time.
Also sort the output_short() fields so the short ones are tried first, for
a minor efficiency gain.
In addition to making the code less repetitive, gcc in my tests now inlines
the parse_fieldv() call in output_short().
It always bothered me a bit that unit-name.[ch] contains so many

With this patch unit-name.[ch] is split into two: the file now contains
only the unit naming related operations, and everything else is split

stuff as well as dbus path and interface name operations.
No functional changes. This just moves code around.
