e46736fbb6 units: use correct path to refer to plymouth
This doesn't really matter, since in non-/usr-merged systems plymouth
needs to be in /bin and on merged ones it doesn't matter, but it is
still prettier to insert the right path, and avoid /bin on merged
systems, since it's just a compat symlink.

0c978faa16 units: drop dependency on systemd-remount-fs.service from systemd-pstore.service
This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.

167241912f units: pull in systemd-pstore.service from sysinit.target
sysinit.target is the target our early boot services are generally
pulled in from, make systemd-pstore.service not an exception of that.

Effectively this doesn't mean much, either way our unit is part of the
initial transaction.

cabc1c6d7a units: add ProtectClock=yes
Add `ProtectClock=yes` to systemd units. Since it implies certain
`DeviceAllow=` rules, make sure that the units have `DeviceAllow=` rules so
they are still able to access other devices. Exclude timesyncd and timedated.

Lennart Poettering
aade0c3b6e Revert "units: make systemd-repart.service installable"
This reverts commit 7e1ed1f3b2.

systemd-repart is not a user service that should be something people
enable/disable, instead it should just work if there's configuration for
it. It's like systemd-tmpfiles, systemd-sysusers, systemd-load-modules,
systemd-binfmt, systemd-systemd-sysctl which are NOPs if they have no
configuration, and thus don't hurt, but cannot be disabled since they
are too deep part of the OS.

This doesn't mean people couldn't disable the service if they really
want to, there's after all "systemctl mask" and build-time disabling,
but those are OS developer facing instead of admin facing, that's how it
should be.

Note that systemd-repart is in particular an initrd service, and so far
enable/disable state of those is not managed anyway via "systemctl
enable/disable" but more what dracut decides to package up and what not.

286fe8ee21 units: do not pull in home.mount from systemd-homed.service
/home is posibly a remote file system. it makes sense to order homed

shouldn't pull it in ourselves, and leave that to users to configure
otherwise.

9fd32ff7d3 units: restore RemainAfterExit=yes in systemd-vconsole-setup.service
This reverts the second part of 8125e8d38e.
The first part was reverted in 750e550eba.
The problem starts when s-v-s.s is pulled in by something that is then pulled
in by sysinit.target. Every time a unit is started, systemd recursively checks
all dependencies, and since sysinit.target is pull in by almost anything, we'll
start s-v-s.s over and over. In particular, plymouth-start.service currently
has Wants=s-v-s.s and After=s-v-s.s.

a3558e7952 units: do not ignore return value from systemd --user
This minus has been there since the unit was added in
d42d27ead9. I think the idea was not cause things
to fail if the user instance doesn't work. But ignoring the return value
doesn't seem to be the right way to approach the problem. In particular, if
the program fails to run, we'll get a bogus fail state, see
https://bugzilla.redhat.com/show_bug.cgi?id=1727895#c1:

with the minus:
$ systemctl start user@1002
Job for user@1002.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status user@1002.service" and "journalctl -xe" for details.

without the minus:
$ systemctl start user@1002
Job for user@1002.service failed because the control process exited with error code.
See "systemctl status user@1002.service" and "journalctl -xe" for details.

f4665664c4 units: disable ProtectKernelLogs for machined
machined needs access to the host mount namespace to propagate bind
mounts created with the "machinectl bind" command. However, the
"ProtectKernelLogs" directive relies on mount namespaces to make the
kernel ring buffer inaccessible. This commit removes the
"ProtectKernelLogs=yes" directive from machined service file introduced
in 6168ae5.

aaaf42cb44 units: add mount for tracefs
Kernel 4.1 separated the tracing system from the debugfs,
actual documentation already points to a different path
that needs this new mount to exist.

the old sysfs path will still be an automount in the debugfs,
created by the kernel (for now).

dc5437c78b journald: add ability to activate by varlink socket

loading this before sysinit.target.

625077264b units: Split modprobing out into a separate service unit
Devices referred to by `DeviceAllow=` sandboxing are resolved into their
corresponding major numbers when the unit is loaded by looking at
`/proc/devices`. If a reference is made to a device which is not yet
available, the `DeviceAllow` is ignored and the unit's processes cannot
access that device.

In both logind and nspawn, we have `DeviceAllow=` lines, and `modprobe`
in `ExecStartPre=` to load some kernel modules. Those kernel modules
cause device nodes to become available when they are loaded: the device
nodes may not exist when the unit itself is loaded. This means that the
unit's processes will not be able to access the device since the
`DeviceAllow=` will have been resolved earlier and denied it.

One way to fix this would be to re-evaluate the available devices and
re-apply the policy to the cgroup, but this cannot work atomically on
cgroupsv1. So we fall back to a second approach: instead of running
`modprobe` via `ExecStartPre`, we move this out to a separate unit and
order it before the units which want the module.

Closes #14322.
Fixes: #13943.

b895fa08e6 Revert "Drop dbus activation stub service"
This reverts commit 07125d24ee.

In contrast to what is claimed in #13396 dbus-broker apparently does
care for the service file to be around, and otherwise will claim
"Service Not Activatable" in the time between systemd starting up the
broker and connecting to it, which the stub service file is supposed to
make go away.

Reverting this makes the integration test suite pass again on host with
dbus-broker (i.e. current Fedora desktop).

Tested with dbus-broker-21-6.fc31.x86_64.

This reverts commit 362c378291.

This commit introduced an ordering loop: remote-cryptsetup.target was both
before and after remote-fs-pre.target. It also globally ordered all cryptsetup
volumes before all mounts. Such global ordering is problematic if people have
stacked storage. Let's look for a different solution.

1dc85eff1d crypsetup: introduce x-initrd.attach option
This option is an indication for PID1 that the entry in crypttab is handled by
initrd only and therefore it shouldn't interfer during the usual start-up and
shutdown process.

It should be primarily used with the encrypted device containing the root FS as
we want to keep it (and thus its encrypted device) until the very end of the
shutdown process, i.e. when initrd takes over.

This option is the counterpart of "x-initrd.mount" used in fstab.

Note that the slice containing the cryptsetup services also needs to drop the
usual shutdown dependencies as it's required by the cryptsetup services.

351de38e4b bootctl: make 'random-seed' handle inability to write system token EFI variable gracefully
Apparently some firmwares don't allow us to write this token, and refuse
it with EINVAL. We should normally consider that a fatal error, but not
really in the case of "bootctl random-seed" when called from the
systemd-boot-system-token.service since it's called as "best effort"
service after boot on various systems, and hence we shouldn't fail
loudly.

Similar, when we cannot find the ESP don't fail either, since there are
systems (arch install ISOs) that carry a boot loader capable of the
random seed logic but don't mount it after boot.
