Currently, when running "systemctl preset-all --root=xxx" in mkosi
to enable/disable units for initrds, the system presets are used.
The problem with this approach is that the system presets are written
for the system, and that is not necessarily ideal for an initrd, but we
still want to use the same packages in the initrd that we install in the
system, so let's introduce a separate directory for initrd presets which
is used to pick up preset files from when we detect that we're configuring
an initrd (by looking for /etc/initrd-release).
We also introduce a systemd preset file for the initrd, which is based on
the system one, except with all the stuff unnecessary for the initrd removed.
I find myself trying to log into a fresh ParticleOS VM started via
systemd-vmspawn all the time, but I don't know its CID. Let's show it on
the getty screen, to make it immediately visible.
By default agetty will not display /run/issue.d/ if /etc/issue exists.
This is quite unfortunate and has actually been fixed upstream in:
https://github.com/util-linux/util-linux/commit/508fb0e7ac103b68531a59db2a4473897853ab52
However, no release has been tagged with this yet, and it doesn't look
like this will happen any time soon. Hence, for now, let's add a
work-around and manually override the issue files to include.
This should be reverted once a new util-linux/agetty release has been
tagged, and found its way into the relevant distributions. Given this is
mostly about cosmetics we do not have to precisely sync the package
updates on this, but only roughly.
Follow-up for dbef4dd4f2. Everything that that
commit says is true, but — at least for me — it wasn't obvious why the code is
correct and we can do fixed-size allocations like new(struct inotify_data, 1).
In sd_event_source.child, we have 5 bools. If we make them each take one byte,
the structure size increases. So let's do that for the three of them, and leave
the other two (less frequently used) squished into the last byte. This allows
more efficient code to be generated, without changing the size of the struct:
$ diff -u <(objdump -S build/src/shared/libsystemd-shared-258.so.0|awk '/^static void source_io_unregister/,/^\}/') \
<(objdump -S build/src/shared/libsystemd-shared-258.so|awk '/^static void source_io_unregister/,/^\}/')
s->io.registered = false;

When OpenSSL is built without UI support, OPENSSL_NO_UI_CONSOLE is
defined. Or, even openssl is built with UI support, people may want to
build systemd without using OpenSSL's UI feature by specifying
-Dc_args='-DOPENSSL_NO_UI_CONSOLE=1'. This adds support for such cases.
Not tested, but hopefully, now systemd can be built with other ssl library,
like BoringSSL, which deos not support UIs.
Closes#38024.
We're still discussing whether we want to remove this or not, but
regardless of whether we end up removing it or not, it's something
we add ourselves and as such should not live in our headers that
override glibc headers, so let's move it to fd-util.h.
This is not something that comes from glibc, but which we invent
ourselves. As such, it should not be part of our overrides of glibc
headers, but instead should be part of one of our own headers, so
let's move it to fd-util.h.

Let's make sure these socket units work as expected by stopping the
related services and making sure the services are started as expected
when a client connects to the corresponding socket.
manager_listen_fds() instructs sd_listen_fds_with_names() to unset
the environment which means that when sd_varlink_server_listen_auto()
is called from manager_start_varlink_server(), when it eventually calls
sd_listen_fds_with_names() it will return zero because the environment
has already been unset in manager_listen_fds().
Fix the issue by not using sd_varlink_server_listen_auto() but instead
keeping track of the varlink socket in manager_listen_fds() and returning
it and passing it to manager_start_varlink_server().
We add D-Bus properties like "*Ex" because we cannot change the D-Bus property
type without breaking backward comapatibility. But those names are only for
D-Bus, not for config file stanzas or the command-line parser. There, we can
change the type, or in other words, there is no type, just a free-form string
whose interpretation we can extend or change. Commit
831f208783 that added ProtectHostnameEx was
confused, because it added ImportCredentialEx in places where parsing of
ImportCredential should be have been extended.
On D-Bus, we send ImportCrednential in preference, and ImportCredentialEx only
when required. This way we send less bytes on the wire and support older
systems that don't understand the new property.
Partially resolves https://github.com/systemd/systemd/issues/37174.
