7a66f21556 core: Add systemd.crash_action= kernel command line argument
Required for integration tests to power off on PID 1 crashes. We
deprecate systemd.crash_reboot and related options by removing them
from the documentation but still parsing them.

78266a54f1 tree-wide: use "_" rather than "-" as separator in kernel cmdline options
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.

7bf52f5d1c Add systemd.default_debug_tty=
Let's allow configuring the debug tty independently of enabling/disabling
the debug shell. This allows mkosi to configure the correct tty while
leaving enabling/disabling the debug tty to the user.

3ccadbce33 homectl: add "firstboot" command
This extends what systemd-firstboot does and runs on first boots only
and either processes user records passed in via credentials to create,
or asks the user interactively to create one (only if no regular user
exists yet).

ec07c3c80b man: add version info
This tries to add information about when each option was added. It goes
back to version 183.

The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.

e503019bc7 tree-wide: when in doubt use greek small letter mu rather than micro symbol
Doesn't really matter since the two unicode symbols are supposedly
equivalent, but let's better follow the unicode recommendations to

116687f267 resolved: read DNS conf also from creds and kernel cmdline
Note that this drops ProtectProc=invisible from
systemd-resolved.service.

This is done because othewise access to the booted "kernel" command line is not
necessarily available. That's because in containers we want to read
/proc/1/cmdline for that.

Fixes: #24103

b66a6e1a58 man: "the initial RAM disk" → "the initrd"
In many places we spelled out the phrase behind "initrd" in full, but this
isn't terribly useful. In fact, no "RAM disk" is used, so emphasizing this
is just confusing to the reader. Let's just say "initrd" everywhere, people
understand what this refers to, and that it's in fact an initramfs image.

Also, s/i.e./e.g./ where appropriate.

Also, don't say "in RAM", when in fact it's virtual memory, whose pages
may or may not be loaded in page frames in RAM, and we have no control over
this.

Also, add <filename></filename> and other minor cleanups.

7a9e0bd031 man: add "History" sections for removed settings
The general idea is that users should be able to figure out if some option
that they see in a config file or on some internet page is something that
systemd knows about. Once users know that, yes, this was an option but has
been deprecated and removed from the documentation, it's much easier for them
to find any docs in old versions if they want to. Or to switch to something
different.

5717062e93 watchdog: Add watchdog pretimeout support
Add support for managing and configuring watchdog pretimeout values if
the watchdog hardware supports it. The ping interval is adjusted to
account for a pretimeout so that it will still ping at half the timeout
interval before a pretimeout event would be triggered. By default the
pretimeout defaults to 0s or disabled.

The RuntimeWatchdogPreSec config option is added to allow the pretimeout
to be specified (similar to RuntimeWatchdogSec). The
RuntimeWatchdogPreUSec dbus property is added to override the pretimeout
value at runtime (similar to RuntimeWatchdogUSec). Setting the
pretimeout to 0s will disable the pretimeout.

08b04ec7e7 veritysetup-generator: add support for veritytab
This adds the support for veritytab.

The veritytab file contains at most five fields, the first four are
mandatory, the last one is optional:
 - The first field contains the name of the resulting verity volume; its
   block device is set up /dev/mapper/</filename>.
 - The second field contains a path to the underlying block data device,
   or a specification of a block device via UUID= followed by the UUID.
 - The third field contains a path to the underlying block hash device,
   or a specification of a block device via UUID= followed by the UUID.
 - The fourth field is the roothash in hexadecimal.
 - The fifth field, if present, is a comma-delimited list of options.
   The following options are recognized only: ignore-corruption,
   restart-on-corruption, panic-on-corruption, ignore-zero-blocks,
   check-at-most-once and root-hash-signature. The others options will
   be implemented later.

Also, this adds support for the new kernel verity command line boolean
option "veritytab" which enables the read for veritytab, and the new
environment variable SYSTEMD_VERITYTAB which sets the path to the file
veritytab to read.

"verity_root_options=" which controls the behaviour of dm-verity by
forwarding options directly to systemd-veritysetup.
