3983fc0227 README: recommend zstd over xz
git archive automatically uses gzip when --output=*.tar.gz is used, but
not for other extensions. Thus we need to invoke the compressor separately :(

It's a good pattern to use a variable for the repeating number, so let's
recommend that.

e8a688178c docs: stop recommending meson compile
With meson-0.60, meson compile stopped working with some targets:

$ meson compile -C build update-man-rules
ERROR: Can't invoke target `update-man-rules`: ambiguous name. Add target type and/or path: `PATH/NAME:TYPE`

This is obviously a regression in meson, but based on a chat with the
maintainers, it seems that there's some disagreement as to whether 'meson
compile' is useful and how exactly it should work. Since we're already at
meson 0.60.3 and this hasn't been fixed, and people generally don't seem to
consider this an issue, let's return to documenting the usual practice of
'ninja -C build' that just works everywhere.

(Since nobody has raised any fuss in systemd, it means that people are
generally using the shorter form during development too. I only noticed
because I pasted a command from the release docs when preparing -rc1.)

277f05872f README: say kernel 4.15 is the minimum recommended
After various long discussions
(https://lists.freedesktop.org/archives/systemd-devel/2022-March/047587.html,
https://lwn.net/Articles/889610/), there is no clear answer what the minimum
version should be. Bumping the version above 3.15 doesn't allow us to make any
significant simplifications (unless we went *much* higher). In particular, even
renameat2() is not fully supported with latest kernel versions, e.g. nfs still
doesn't have it. And the bpf stuff is optional anyway. So let's just say that
4.15 is what we recommend, because it provides fairly complete cgroups-v2, but
without any removals of compat in the code.

ba4e0427e9 time-util: assume CLOCK_BOOTTIME always exists
Let's raise our supported baseline a bit: CLOCK_BOOTTIME started to work
with timerfd in kernel 3.15 (i.e. back in 2014), let's require support
for it now.

This will raise our baseline only modestly from 3.13 → 3.15.

baec7d782b meson: Drop required libfdisk version to 2.32
We initially pinned this to 2.33 in
e71f5585b9 because libfdisk 2.32 in
CentOS 8 didn't have
2f35c1ead6
backported.

If we check now, we can see it has been backported
(https://git.centos.org/rpms/util-linux/blob/c8s/f/SOURCES/0048-libfdisk-count-gaps-to-possible-size-when-resize.patch)
which means we can drop the required version to 2.32 instead of 2.33.

53f69d671c sd-boot: Require gnu-efi 3.0.5
This version is from 2017 and should be stale enough to not cause
an outrage. All the relevant distros have it or a newer version.

We also already depend on some symbols defined in 3.0.5 anyway,
so let's take the opportunity to reduce our missing_efi.h
baggage.

6d825ab2d4 rpm: use a helper script to actually invoke systemctl commands
Instead of embedding the commands to invoke directly in the macros,
let's use a helper script as indirection. This has a couple of advantages:

- the macro language is awkward, we need to suffix most commands by "|| :"
  and "\", which is easy to get wrong. In the new scheme, the macro becomes
  a single simple command.
- in the script we can use normal syntax highlighting, shellcheck, etc.
- it's also easier to test the invoked commands by invoking the helper
  manually.
- most importantly, the logic is contained in the helper, i.e. we can
  update systemd rpm and everything uses the new helper. Before, we would
  have to rebuild all packages to update the macro definition.

This raises the question whether it makes sense to use the lua scriptlets when
the real work is done in a bash script. I think it's OK: we still have the
efficient lua scripts that do the short scripts, and we use a single shared
implementation in bash to do the more complex stuff.

The meson version is raised to 0.47 because that's needed for install_mode.
We were planning to raise the required version anyway…

44ff8df777 Drop dependency on m4
m4 was hugely popular in the past, because autotools, automake, flex, bison and
many other things used it. But nowadays it much less popular, and might not even
be installed in the buildroot. (m4 is small, so it doesn't make a big difference.)

(FWIW, Fedora dropped make from the buildroot now,
https://fedoraproject.org/wiki/Changes/Remove_make_from_BuildRoot. I think it's
reasonable to assume that m4 will be dropped at some point too.)

The main reason to drop m4 is that the syntax is not very nice, and we should
minimize the number of different syntaxes that we use. We still have two
(configure_file() with @FOO@ and jinja2 templates with {{foo}} and the
pythonesque conditional expressions), but at least we don't need m4 (with
m4_dnl and `quotes').

9afd5e7b97 Deprecate builds with split-usr, prepare for removal
There is no technical reason to support systems with split-usr, except for
backwards compatibility. Even though systemd itself makes an effort to support
this, many other tools aren't as careful. Despite those efforts, we
(collectively) get it wrong often, because doing it "wrong" on systems with
merged-usr has no consequences. Since almost all developers are on such
systems, any issues are only discovered late. Supporting this split-usr mode
makes both code and documentation more complicated. The split is purely
artificial and has no justification except to allow old installation to not
update. Mechanisms to update existing systems are available though: Fedora
did that in https://fedoraproject.org/wiki/Features/UsrMove, Debian has
the usrmerge package.

The next version of Debian will only support systems with split-usr=false,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=978636#178:

  The Technical Committee resolves that Debian 'bookworm' should
  support only the merged-usr root filesystem layout, dropping support
  for the non-merged-usr layout.

Let's start warning if split-usr mode is used, in preparation to removing the
split in one of the future releases.

38ccb55731 nss-mymachines: drop support for UID/GID resolving
Now that we make the user/group name resolving available via userdb and
thus nss-systemd, we do not need the UID/GID resolving support in
nss-mymachines anymore. Let's drop it hence.

We keep the module around, since besides UID/GID resolving it also does
hostname resolving, which we care about. (One of those days we should
replace that by some Varlink logic between
nss-resolve/systemd-resolved.service too)

The hooks are kept in the NSS module, but they do not resolve anything
anymore, in order to keep compat at a maximum.

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.

07125d24ee Drop dbus activation stub service
This fixes the following problem:

> At the very end of the boot, just after the first user logs in
> (usually using sddm / X) I get the following messages in my logs:
> Nov 18 07:02:33 samd dbus-daemon[2879]: [session uid=1000 pid=2877] Activated service 'org.freedesktop.systemd1' failed: Process org.freedesktop.systemd1 exited with status 1
> Nov 18 07:02:33 samd dbus-daemon[2879]: [session uid=1000 pid=2877] Activated service 'org.freedesktop.systemd1' failed: Process org.freedesktop.systemd1 exited with status 1

These messages are caused by the "stub" service files that systemd
installs. It installed them because early versions of systemd activation
required them to exist.

Since dbus 1.11.0, a dbus-daemon that is run with --systemd-activation
automatically assumes that o.fd.systemd1 is an activatable
service. As a result, with a new enough dbus version,
/usr/share/dbus-1/services/org.freedesktop.systemd1.service and
/usr/share/dbus-1/system-services/org.freedesktop.systemd1.service should
become unnecessary, and they can be removed.

dbus 1.11.0 was released 2015-12-02.

Removing the environment variable causes problems, e.g. Xfce and Chromium and

one by one, but removing the variable right now is causing too many problems.
