e5a8b4b593 bootctl: tweak "bootctl update" to be a NOP when boot loader is already current and --graceful is given
Previously, the "bootctl update" logic would refrain from downrgading a
boot loader, but if the boot loader that is installed already matched
the version we could install we'd install it anyway, under the
assumption this was effectively without effect. This behaviour was handy
while developing boot loaders, since installing a modified boot loader
didn't require a version bump.

However, outside of the systems of boot loader developers I don't think
this behaviour makes much sense: we should always emphasize doing
minimal changes to the ESP, hence when an update is supposedly not
necessary, then don't do it. Only update if it really makes sense, to
minimize writes to the ESP. Updating the boot loader is a good thing
after all, but doing so redundantly is not.

Also, downgrade the message about this to LOG_NOTICE, given this
shouldn't be a reason to log.

Finally, exit cleanly in this cases (or if another boot loader is
detected)

7eea910d24 bootctl: extend --make-machine-id-directory= documentation a bit
The directory might not be created in the ESP but in the extended boot
loader partition, hence don#t claim otherwise.

Also, give a brief reason why the concept exists at all.

Link up machine-id man page.

c4b843473a bootctl: add @current/@oneshot/@default targets to set-default/set-oneshot
Using `bootctl set-default @current` will set the default loader entry
to the currently booted entry as read from the `LoaderEntrySelected` EFI
variable.

Also `bootctl set-oneshot @current` will set the oneshot loader entry to
the current booted entry.

Correspondingly `@default` and `@oneshot` can be used to read from the
LoaderEntryDefault and LoaderEntryOneshot EFI variables.

64a7fcc5cd bootctl: separate boot loader specific commands in man and --help
bootctl implements three types of operation: those that work with an EFI
boot loader, those which work with any EFI boot loader that implements
the boot loader spec + interface, and finally those specific to sd-boot.
Previously the --help text and the man page mixed them all up. Let's put
them clearly in three separate sections however, to communicate clearly
what is supposed to work everywhere, and what is specific to
systemd-boot or boot loaders implementing the two specs.

This adjusts wording here and there, but is mostly just about
re-ordering existing docs, and putting them under new sections.

351de38e4b bootctl: make 'random-seed' handle inability to write system token EFI variable gracefully
Apparently some firmwares don't allow us to write this token, and refuse
it with EINVAL. We should normally consider that a fatal error, but not
really in the case of "bootctl random-seed" when called from the
systemd-boot-system-token.service since it's called as "best effort"
service after boot on various systems, and hence we shouldn't fail
loudly.

Similar, when we cannot find the ESP don't fail either, since there are
systems (arch install ISOs) that carry a boot loader capable of the
random seed logic but don't mount it after boot.

Fixes: #13603

2536752dda Rename "system-options" to "systemd-efi-options"
This makes the naming more consistent: we now have
bootctl systemd-efi-options,
$SYSTEMD_EFI_OPTIONS
and the SystemdOptions EFI variable.

(SystemdEFIOptions would be redundant, because it is only used in the context
of efivars, and users don't interact with that name directly.)

bootctl is adjusted to use 2sp indentation, similarly to systemctl and other
programs.

Remove the prefix with the old name from 'bootctl systemd-efi-options' output,
since it's redundant and we don't want the old name anyway.

fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

818bf54632 tree-wide: drop 'This file is part of systemd' blurb
This part of the copyright blurb stems from the GPL use recommendations:

https://www.gnu.org/licenses/gpl-howto.en.html

The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.

hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
