Instead of running meson install and hoping for the best, let's build
distribution packages from the downstream packaging specs. This gets
us the following:
- Vastly simplified mkosi scripts since we don't need a separate initrd
image anymore but can just reuse the default mkosi initrd.
- Almost everything can move to the base image as its not the basis
anymore for the initrd and as such we don't need to care about the
size anymore.
- The systemd packages that get pulled in as dependencies of other
packages get properly uninstalled and replaced with our packages that
we built instead of just installing on top of an existing systemd
installation with no guarantee that everything from that previous
installation was removed.
- Much better testing coverage as what we're testing is much closer
to what will actually be deployed in distributions.
- Immediate feedback if something we change breaks distribution packaging
- We get integration with the distribution for free as we'll automatically
use the proper directories and such instead of having to hack this
into a mkosi build script.

Whenever a home directory is in a locked state, accessing the files of
the home directory is extremely likely to cause the thread to hang. This
will put the session in a strange state, where some threads are hanging
due to file access and others are not hanging because they are not
trying to access any of the user's files.
This can lead to a whole slew of consequences. For example, imagine a
likely situation where the Wayland compositor is not hanging, but the
user's open apps are. Eventually, the compositor will detect that none
of the apps are responding to its pings, assume that they're frozen
(which they are), and kill them. The systemd user instance can end up in
a similarly confused state and start killing user services. In the worst
case, killing an app at an unexpected moment can lead to data loss.
The solution is to suspend execution of the whole user session by
freezing the user's slice.
Previously, we'd only freeze user.slice in the case of s2h, because we
didn't want the user session to resume while systemd was transitioning
from suspend to hibernate.
This commit extends this freezing behavior to all sleep modes.
We also have an environment variable to disable the freezing behavior
outright. This is a necessary workaround for someone that has hooks
in /usr/lib/systemd/system-sleep/ which communicate with some
process running under user.slice, or if someone is using the proprietary
NVIDIA driver which breaks when user.slice is frozen (issue #27559)

This is a kinda a follow-up for ce266330fc: it
makes resolved authoritative on our local hostname, and never contacts
DNS anymore for it.
We effectively already were authoritative for it, except if the user
queried for other RR types than just A/AAAA. This closes the gap and
refuses routing other RR type queries to DNS.
Fixes: #23662
It turns out it's mostly PKCS11 that supports the URI format,
and other engines just take files. For example the tpm2-tss-openssl
engine just takes a sealed private key file path as the key input,
and the engine needs to be specified separately.
Add --private-key-source=file|engine:foo|provider:bar to
manually specify how to use the private key parameter.

These will be used by display managers to pre-select the user's
preferred desktop environment and display server type. On homed, the
display manager will also be able to set these fields to cache the
user's last selection.
Most of our kernel cmdline options use underscores as word separators in
kernel cmdline options, but there were some exceptions. Let's fix those,
and also use underscores.
Since our /proc/cmdline parsers don't distinguish between the two
characters anyway this should not break anything, but makes sure our own
codebase (and in particular docs and log messages) are internally
consistent.
This reverts commit 5e8ff010a1.
This broke all the URLs, we can't have that. (And actually, we probably don't
_want_ to make the change either. It's nicer to have all the pages in one
directory, so one doesn't have to figure out to which collection the page
belongs.)
We're documenting the behavior of blob directories here. These docs
refer to things that aren't yet implemented at the time of the commit, but will be later in the same PR.
Let's make sure that versions generated by meson-vcs-tag.sh always
sort higher than official and stable releases. We achieve this by
immediately updating the meson version in meson.build after a new
release. To make sure this version always sorts lower than future
rcs, we suffix it with "~devel" which will sort lower than "~rcX".
The new release workflow is to update the version in meson.build
for each rc and the official release and to also update the version
number after a new release to the next development version.
The full version is exposed as PROJECT_VERSION_FULL and used where
it makes sense over PROJECT_VERSION.
We also switch to reading the version from a meson.version file in
the repo instead of hardcoding it in meson.build. This makes it
easier to access both inside and outside of the project.
The meson-vcs-tag.sh script is rewritten to query the version from
meson.version instead of passing it in via the command line. This
makes it easier to use outside of systemd since users don't have to
query the version themselves first.
This adds fields to the user record logic to allow a "fallback" home
directory and shell to be set as part of the "status" section of the
user record, i.e. supplied by the manager of the user record.
The idea is that if the fallback homedir/shell is set it will take
precedence over the real one in most ways.
Usecase: let's try to make ssh logins into homed directories work.
systemd-homed would set a fallback shell/homedir for inactive home dirs.
Thus, when ssh logins take place via key auth, we can allow them, and
these fallback session params would be used because the real home cannot
be activated just yet becasue we cannot acquire any password for it from
the user.
This field is like preferredLanguage, but takes a priority list of
languages instead. If an app isn't translated into a user's primary
language, it can fall back to one of the other languages in the list
thus making the app more accessible to the user.
For instance: in my experience, many Ukrainians are fluent in Russian,
often significantly better than English (especially if they are of a
generation that grew up during the USSR). Such a person might set this
new variable to ["uk_UA.UTF-8", "ru_UA.UTF-8"] so that software that
lacks Ukrainian translations will first try Russian translations before
defaulting to English.

tilde sorts lower in the version comparison spec:
https://uapi-group.org/specifications/specs/version_format_specification/
➜ systemd git:(strip) systemd-analyze compare-versions 249\~rc1 249
249\~rc1 < 249
➜ systemd git:(strip) systemd-analyze compare-versions 249-rc1 249
249-rc1 > 249
Also update tools/meson-vcs-tag.sh to use carets instead of hyphens
for the git part of the version as carets are allowed to be part of
a version by pacman while hyphens are not and both sort higher than
a version without the git part.
When running an image that cannot be mounted (e.g.: key missing intentionally
for development purposes), there's a retry loop that takes some time
and slows development down. Add an env var to disable it.
It silly for our docs to say that they aren't when we added support for this a
few years ago.
Also, drop some mentions of "runtime". This implied that those values can be
changed almost at will, but actually, they can only be meaningfully changed
_before_ the allocations are made.
varlink_server_listen_auto() is supposed to be the one-stop solution for
turning simple command line tools into IPC services. They aren't easy to
test/debug however, since you have to invoke them through a service
manager.
Let's make this easier: if the SYSTEMD_VARLINK_LISTEN env var is set,
let's listen on the socket specified therein. This makes things easier
to gdb: just run the service from the cmdline.
Both building and booting a directory image is much faster than
building or booting a disk image so let's default to a directory
image.
In CI, we stick to a disk image to make sure that keeps working as
well.
The only extra dependency this introduces is virtiofsd which is
packaged in all distributions except Debian stable. For users
hacking on systemd on Debian stable, a disk image can be built by
writing the following to mkosi.local.conf:
```
[Output]
Format=disk
```
