e053f49272 units: enable systemd-network-generator by default
It is used by udevd and networkd. Since udevd is enabled statically, let's also
change the preset to "on". networkd is opt-in, so let's pull in the generator
when enabling networkd too.

71c8bf2837 boot: optionally update sd-boot on boot
Boot loaders are software like any other, and hence muse be updated in
regular intervals. Let's add a simple (optional) service that updates
sd-boot automatically from the host if it is found installed but
out-of-date in the ESP.

Note that traditional distros probably should invoke "bootctl update"
directly from the package scripts whenver they update the sd-boot
package. This new service is primarily intended for image-based update
systems, i.e. where the rootfs or /usr are atomically updated in A/B
style and where the current boot loader should be synced into the ESP
from the currently booted image every now and then. It can also act as
safety net if the packaging scripts in classic systems are't doing the
bootctl update stuff themselves.

Since updating boot loaders mit be a tiny bit risky (even though we try
really hard to make them robust, by fsck'ing the ESP and mounting it only on
demand, by doing updates mostly as single file updates and by fsync()ing
heavily) this is an optional feature, i.e. subject to "systemctl
enable". However, since it's the right thing to do I think, it's enabled
by default via the preset logic.

Note that the updating logic is implemented gracefully: i.e. it's a NOP
if the boot loader is already new enough, or was never installed.

7139e9d9a3 preset: don't enable proc-sys-fs-binfmt_misc.mount
The proc-sys-fs-binfmt_misc.mount unit should not be enabled by
preset-all because it should only be used as fallback in case
proc-sys-fs-binfmt_misc.automount cannot be used on a system.  In these
cases it should be enabled manually by an administrator.

548af942b8 Revert "presets: "disable" all passive targets by default"
This reverts commit 61c3e2c8bf.

The original commit doesn't make sense to me, none of the listed units
have an [Install] section, they hence are not subject to enable/disable
and hence not preset either. This commit hence has no effect whatsoever,
let's undo it to avoid further confusion.

9e27fd321c preset: let's clean up preset list a bit
let's make sure we list all singleton units we define in the preset
list, either as disable or as enable. Only four were missing, let's add
them in.

Also, let's group the pstore one with the other ones that are enabled,
right at the top.

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.

ead7af3093 units: make systemd-userdbd.{socket,service} installable
It's lightweight and generally useful, so it should be enabled by default. But
users might want to disable it for whatever reason, and things should be fine
without it, so let's make it installable so it can be disabled if wanted.

Fixes #15175.

5ef9eda17f units: make systemd-homed.service installable
Fixes #15083. Users might want to disable homed if not used to save resources.

7e1ed1f3b2 units: make systemd-repart.service installable
This essentially adds another layer of configurability:
build disable, this, presence of configuration. The default is
set to enabled, because the service does nothing w/o config.

5926ea0a68 presets: enable systemd-pstore.service by default
It has no effect is the pstore is not used, and prevents the non-volatile
storage from filling up if is used by the kernel.

61c3e2c8bf presets: "disable" all passive targets by default
Officially we default to a "enable *", even though pretty much everybody
overrides this with "disable *". We have a bunch of targets and services which
should not be enabled by default. In case the default policy is not overriden,
our passive units would be enabled by presets, which is generally not useful at
all. So let's explicitly mark them as disabled.

Note that this effectively changes very little. E.g. on Fedora, all the units
listed in this patch were "disabled" already.

Fixes #14648.

96b2fb93c5 tree-wide: beautify remaining copyright statements
Let's unify an beautify our remaining copyright statements, with a
unicode ©. This means our copyright statements are now always formatted
the same way. Yay.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

cfdda37c9f Hook up systemd-tmpfiles as user units
An explicit --user switch is necessary because for the user@0.service instance
systemd-tmpfiles is running as root, and we need to distinguish that from
systemd-tmpfiles running in systemd-tmpfiles*.service.

Fixes #2208.

v2:
- restore "systemd-" prefix
- add systemd-tmpfiles-clean.{service,timer}, systemd-setup.service to
  systemd-tmpfiles(8)

e783f95718 Rename "system-preset" source dir to "presets"
I want to add presets/user/ later. This mirrors the layout for units:
we have units/ and units/user. The advantage is that we avoid having yet
another directory at the top level.
