9d03637404 units: let systemd --user manage its own memory pressure handling
Let's make things systematic: the per-user and the per-system manager
should manage their own memory pressure, as they are, well, managers of
things.

This is particularly relevant and the per-user service manager should
watch its own "init.scope" subcgroup, instead of the main service unit
cgroup, and hence $MEMORY_PRESSURE_WATCH as set by the per-system
service manager would simply be wrong.

7ef09e2099 units: change assert to condition to skip running in initrd/os
These units are also present in the initrd, so instead of an assert,
just use a condition so they are skipped where they need to be skipped.

e4c7b5f517 core: split system/user job timeouts and make them configurable
Config options are -Ddefault-timeout-sec= and -Ddefault-user-timeout-sec=.
Existing -Dupdate-helper-user-timeout= is renamed to -Dupdate-helper-user-timeout-sec=
for consistency. All three options take an integer value in seconds. The
renaming and type-change of the option is a small compat break, but it's just
at compile time and result in a clear error message. I also doubt that anyone was
actually using the option.

This commit separates the user manager timeouts, but keeps them unchanged at 90 s.
The timeout for the user manager is set to 4/3*user-timeout, which means that it
is still 120 s.

Fedora wants to experiment with lower timeouts, but doing this via a patch would
be annoying and more work than necessary. Let's make this easy to configure.

04959faa63 generators: optionally, measure file systems at boot
If we use gpt-auto-generator, automatically measure root fs and /var.

Otherwise, add x-systemd.measure option to request this.

50072ccf1b units: rework growfs units to be just a regular unit that is instantiated
The systemd-growfs@.service units are currently written in full for each
file system to grow. Which is kinda pointless given that (besides an
optional ordering dep) they contain always the same definition. Let's
fix that and add a static template for this logic, that the generator
simply instantiates (and adds an ordering dep for).

This mimics how systemd-fsck@.service is handled. Similar to the wait
that for root fs there's a special instance systemd-fsck-root.service
we also add a special instance systemd-growfs-root.service for the root
fs, since it has slightly different deps.

072c8f6505 units: measure /etc/machine-id into PCR 15 during early boot
We want PCR 15 to be useful for binding per-system policy to. Let's
measure the machine ID into it, to ensure that every OS we can
distinguish will get a different PCR (even if the root disk encryption
key is already measured into it).

2aba77057e journal: give the ability to enable/disable systemd-journald-audit.socket
Before this patch the only way to prevent journald from reading the audit
messages was to mask systemd-journald-audit.socket. However this had main
drawback that downstream couldn't ship the socket disabled by default (beside
the fact that masking units is not supposed to be the usual way to disable
them).

dd0ab174c3 pid1: make sure we send our calling service manager RELOADING=1 when reloading
And send READY=1 again when we are done with it.

We do this not only for "daemon-reload" but also for "daemon-reexec" and
"switch-root", since from the perspective of an encapsulating service
manager these three operations are not that different.

882b011277 units: condition systemd-networkd-wait-online.service like systemd-networkd.service
This adds the same condition that systemd-networkd.service already
carries also to systemd-networkd-wait-online.service. Otherwise we'll
potentially see some logs we'd rather not see about a service we BindTo=
not running. Or in other words, if service X binds to Y then X should be
at least as conditioned as Y.

116687f267 resolved: read DNS conf also from creds and kernel cmdline
Note that this drops ProtectProc=invisible from
systemd-resolved.service.

This is done because othewise access to the booted "kernel" command line is not
necessarily available. That's because in containers we want to read
/proc/1/cmdline for that.

921fc451cb units: rename/rework systemd-boot-system-token.service → systemd-boot-random-seed.service
This renames systemd-boot-system-token.service to
systemd-boot-random-seed.service and conditions it less strictly.

Previously, the job of the service was to write a "system token" EFI
variable if it was missing. It called "bootctl --graceful random-seed"
for that. With this change we condition it more liberally: instead of
calling it only when the "system token" EFI variable isn't set, we call
it whenever a boot loader interface compatible boot loader is used. This
means, previously it was invoked on the first boot only: now it is
invoked at every boot.

This doesn#t change the command that is invoked. That's because
previously already the "bootctl --graceful random-seed" did two things:
set the system token if not set yet *and* refresh the random seed in the
ESP. Previousy we put the focus on the former, now we shift the focus to
the latter.

With this simple change we can replace the logic
f913c784ad added, but from a service that
can run much later and doesn't keep the ESP pinned.

ce7dcfd6b0 units: pull in loop.ko and dm-mod.ko before repart
We want to make use of that when formatting file systems, hence let's
pull in these modules explicitly.

(This is necessary because we are an early boot service that might run
before systemd-tmpfiles-dev.service, which creates /dev/loop-control and
/dev/mapper/control.)

Alternatively we could just order ourselves after
systemd-tmpfiles-dev.service, but I think there's value in adding an
explicit minimal ordering here, since we know what we'll need.
