0d315ca6e7 docs: remove /dev/tty* confusion
The text said /dev/tty* as a whole was the VT subsystem and that VT is
not supported in containers.

But that's not accurate as /dev/tty* will match /dev/tty too and that
one device node is special and is not related to VT: it always points to
the current process own controlling tty, regardless what that is.

hence, rewrite /dev/tty* as /dev/tty[0-9]*.

f000edf9ea docs: fix descriptions in discoverable partitions
00db9a114e ("docs: generate table from header using a script") got the
descriptions for the partition types mixed up.  After that change, the
spec claimed, for example, that the /usr partition should contain
"dm-verity integrity hash data for the matching root partition", and
that the /usr verity partition should be of type "Any native, optionally
in LUKS".  This made the spec an extremely confusing read before I
figured out what must have happened!

I've gone through the table as it existed prior to 00db9a114e, and moved
the descriptions around in the script that generates the table until
they matched up with what they used to be.  Then I regenerated the
table from the fixed script.

00db9a114e docs: generate table from header using a script
This adds a helper script:
$ python3 tools/list-discoverable-partitions.py <src/shared/gpt.h
<!-- generated with tools/list-discoverable-partitions.py -->
| Partition Type UUID | Name | Allowed File Systems | Explanation |
|---------------------|------|----------------------|-------------|
| _Root Partition (Alpha)_ | `6523f8ae-3eb1-4e2a-a05a-18b695ae656f` | [Root Partition] | [Root Partition more] |
| _Root Partition (ARC)_ | `d27f46ed-2919-4cb8-bd25-9531f3c16534` | ditto | ditto |
...

The output can be pasted into the markdown file. I think this works better than
trying to match the two lists by hand.

1fb2d8fcb6 docs: invite people to define GPT partition types for all archs now
The discovery partitions spec so far suggested we should define
arch-specific partition type uuids only for archs that have EFI. Let's
change that and invite people to define them for any arch. Why? Even if
GPT is defined as part of the UEFI spec it's quite useful independently
of it, too. Specifically, our image dissection logic makes use of it,
i.e. systemd-nspawn, systemd-gpt-auto-generator, systemd-repart,
RootImage=, portable services, and so on. None of these tools are
related to UEFI in any way.

Hence, let's open this up.

a6d1760024 build: preserve correct mode when generating files via jinja2
When using "capture : true" in custom_target()s the mode of the source
file is not preserved when the generated file is not installed and so
needs to be tweaked manually. Switch from output capture to creating the
target file and copy the permissions from the input file.

596e447076 Reintroduce ExitType
This introduces `ExitType=main|cgroup` for services.
Similar to how `Type` specifies the launch of a service, `ExitType` is
concerned with how systemd determines that a service exited.

- If set to `main` (the current behavior), the service manager will consider
  the unit stopped when the main process exits.

- The `cgroup` exit type is meant for applications whose forking model is not
  known ahead of time and which might not have a specific main process.
  The service will stay running as long as at least one process in the cgroup
  is running. This is intended for transient or automatically generated
  services, such as graphical applications inside of a desktop environment.

Motivation for this is #16805. The original PR (#18782) was reverted (#20073)
after realizing that the exit status of "the last process in the cgroup" can't
reliably be known (#19385)

This version instead uses the main process exit status if there is one and just
listens to the cgroup empty event otherwise.

The advantages of a service with `ExitType=cgroup` over scopes are:
- Integrated logging / stdout redirection
- Avoids the race / synchronisation issue between launch and scope creation
- More extensive use of drop-ins and thus distro-level configuration:
  by moving from scopes to services we can have drop ins that will affect
  properties that can only be set during service creation,
  like `OOMPolicy` and security-related properties
- It makes systemd-xdg-autostart-generator usable by fixing [1], as obviously
  only services can be used in the generator, not scopes.

9214f2999b CODING_STYLE: allow joined variable declarations and function calls
… but only for a single variable.

The guidelines already allowed declaring variables at the point of
initialization. But not making a function call to do that. Let's allow that
now.  The existing style of declaring and initializing seperate is still
allowed, and whatever makes most sense should be used.

All other backends allow placing the data store at arbitrary places,
let's allow this too for the CIFS backend. This is particularly useful
for testing.
