When an exec directory is shared between services, this allows one of the
service to be the producer of files, and the other the consumer, without
letting the consumer modify the shared files.
This will be especially useful in conjunction with id-mapped exec directories
so that fully sandboxed services can share directories in one direction, safely.
systemd-sysupdated is still unstable and we'd like to make breaking
changes to it even after the v257 release, so we document it as such and
disable building it by default in release builds. The distro can still
opt-in, and we still build it in developer mode so it has CI coverage
This commit introduces a build-time option to enable/disable sysupdated
separately from sysupdate. 'auto' translated to enabled by default in
developer builds.
There's still some breaking changes we want to make to sysupdated, but
they'll potentially take months and we don't want to block the systemd
release for that long. So, we can instead mark sysupdate's API as
unstable
Let's ramp up security for system user accounts, at least where
possible, by creating them fully locked (instead of just with an invalid
password). This matters when taking non-password (i.e. SSH) logins into
account.

We should avoid unnecessary abbreviations for such messages, and this
puts a maximum limit on things, hence it should indicate this in the
name.
Moreover, matches is a bit confusing, since most people will probably
call "busctl monitor" without any match specification, i.e. zero
matches, but that's not what was meant here at all.
Also, add a brief switch for this (-N) since I figure in particular
"-N1" might be a frequent operation people might want to use.

We are going to output a series of JSON objects, hence let's
automatically enable JSON-SEQ output mode, as we usually do.
"jq --seq" supports this natively, hence this should not really restrict
us.

This applies the existing SocketUser=/SocketGroup= options to units
defining a POSIX message queue, bringing them in line with UNIX
sockets and FIFOs. They are set on the file descriptor rather than
a file system path because the /dev/mqueue path interface is an
optional mount unit.
This commit adds two settings private and strict to
the ProtectControlGroups= property. Private will unshare the cgroup
namespace and mount a read-write private cgroup2 filesystem at /sys/fs/cgroup.
Strict does the same except the mount is read-only. Since the unit is
running in a cgroup namespace, the new root of /sys/fs/cgroup is the unit's
own cgroup.
We also add a new dbus property ProtectControlGroupsEx which accepts strings
instead of boolean. This will allow users to use private/strict via dbus
and systemd-run in addition to service files.
Note private and strict fall back to no and yes respectively if the kernel
doesn't support cgroup2 or system is not using unified hierarchy.

The goal of RestartMode=direct is to make restarts invisible
to dependents, so auto restart jobs shouldn't bring them down
at all. So far we only skipped going through failed/dead states
in service_enter_dead(), i.e. the unit would never be considered
dead. But when constructing restart transaction, the stop job
would be propagated to dependents. Consider the following 2 units:
dependent.target:
[Unit]
BindsTo=a.service
After=a.service
a.service:
[Service]
ExecStart=bash -c 'sleep 100 && exit 1'
Restart=on-failure
RestartMode=direct
Before this commit, even though BindsTo= isn't triggered since
a.service never failed, when a.service auto-restarts, dependent.target
is also restarted. Let's suppress it by using JOB_REPLACE instead of
JOB_RESTART_DEPENDENCIES in service_enter_restart().
Fixes#34758
The example above is subtly different from the original report,
to illustrate that the new behavior makes sense for less exotic
use cases too.
No functional change, but let's print yes/no rather than on/off in systemd-analyze.
Similar to 2e8a581b9c and
edd3f4d9b7.
(Note, the commit messages of those commits are wrong, as
parse_boolean() supports on/off anyway.)
This makes use of the infra introduced in 229d4a9806 to indicate visually on each prompt that we are in superuser mode temporarily.
pick ad5de3222f userdbctl: add some basic client-side filtering
This adds some basic client-side user/group filtering to "userdbctl":
1. by uid/gid min/max
2. by user "disposition" (i.e. show only regular users with "userdbctl
user -R")
3. by fuzzy name (i.e. search by substring/levenshtein of user name,
real name, and other identifiers of the user/group record).
In the long run we also want to support this server side, but let's
start out with doing this client-side, since many backends won't support
server-side filtering anytime soon anyway, so we need it in either case.
Clients should be able to know if the idle logic is available on a
session without secondary knowledge about the session class. Let's hence
expose a property for that.
Similar for the screen lock concept.

This option will control the use of DNR for choosing DNS servers on the
link. Defaults to the value of UseDNS so that in most cases they will be
toggled together.
