db26d8025e kernel-install: support full set of config files and drop-ins
This brings the handling of config for kernel-install in line with most of
systemd, i.e. we search the set of paths for the main config file, and the full
set of drop-in paths for drop-ins.

This mirrors what 07f5e35fe7 did for udev.conf.
That change worked out fine, so I hope this one will too.

The update in the man page is minimal. I think we should split out a separate
page for the config file later on.

One motivating use case is to allow a drop-in to be created for temporary
config overrides and then removed after the operation is done.

758d14767d kernel-install: make "inspect" work more like "add" regarding omission of parameters

9d9e99a8f0 kernel-install: make version/kernel image parameters optional for "add"
Let's make kernel-install a bit easier to use:

If the kernel version is not specified, let's imply "uname -r", so that
we regnerate the entries for the current kernel.

If the kernel image is not specified let's imply using
/usr/lib/modules/$version/vmlinuz, i.e. the location distros like Fedora
drop the kernel into, which we generally recommend people to use.

If the kernel is not found there, don't try to automatically pick the
kernel path, and fail, as before.

bdd36c003d kernel-install: Add --json option for inspect verb
In mkosi, we can't use kernel-install directly but we do want to
mimick its behavior as much as possible. Let's make that easier by
making it easy to fetch data from kernel-install as JSON.

To get all the necessary data, we extend the inspect verb to also
allow passing in a kernel version and initrds, to mimick the "add"
verb. The kernel version is used to determine the "Entry Directory",
and in absence of auto-detection of kernel version in kernel-install
we have to allow users to pass it.

We also add --no-pager while we're at it.

7a9d86bceb man/kernel-install: fix formatting and document /etc/kernel/devicetree
Each filename should be a separate <term>, so that they separated in the
formatted text. Also, we list files in documentation in priority order, but
here they were in reverse order. Also, rework the description of
$KERNEL_INSTALL_CONF_ROOT to say that it makes kernel-install not look at the
other files. This requires some more words, so make this a separate paragraph
and refer from individual items to it. Also, drop some sentences with "Read by
...", they were already outdated.

Partial fix for #28771.

eb25844f83 kernel-install: describe usage as installkernel
For us, this is a compatibility mode, but most likely it is there to stay: the
kernel Makefile's install target expects to be able to call /bin/installkernel.
We want people who build their own kernels to use this, so that they use
kernel-install and get support for all the functionality provided by it,
including building of UKIs and other new features. So let's actually advertise
that this exists and works.

This can be useful if one wants to use mkinitcpio / Dracut to generate the initrd, but without creating the UKI so this can be left for e.g. ukify or something else.

Seems OK to me. The full stop is there and has been for at least a few years. And we use <option> for the markup, which is appropriate here.

> Man page: crypttab.5
> Issue 1:  Missing fullstop
> Issue 2:  I<cipher=>, I<hash=>, I<keyfile-offset=>, I<keyfile-size=>, I<size=> → B<cipher=>, B<hash=>, B<keyfile-offset=>, B<keyfile-size=>, B<size=>

Same.

Fixed.

Fixed.

This is a bit awkward, but I'm not sure how to fix it.

> Man page: kernel-install.8
> Issue:    methods a fallback → methods fallback

It was correct, but I added a comma to make the sense clearer.

> Man page: loader.conf.5

"one of" would sound strange. "One this and one that" is OK.

> Man page: loader.conf.5
> Issue:    systemd-boot → B<systemd-boot>(7)

Fixed.

> Man page: logind.conf.5
> Issue:    systemd-logind → B<systemd-logind>(8)

We use <filename>systemd-logind</> on subsequent references… I think that's good enough.

> Man page: nss-myhostname.8
> Issue:    B<getent> → B<getent>(1)

Fixed.

> Man page: nss-resolve.8
> Issue:    B<systemd-resolved> → B<systemd-resolved>(8)

The first reference does this, subsequent are shorter.

> Man page: os-release.5

Updated.

> Man page: pam_systemd_home.8
> Issue:    auth and account use "reason", while session and password do not?

Reworded.

> Man page: portablectl.1

Updated.

> Man page: repart.d.5
> Issue:    The partition → the partition

Fixed.

> Man page: repart.d.5
> Issue:    B<systemd-repart> → B<systemd-repart>(8)

The first reference does this. I also change this one, because it's pretty far down in the text.

> Man page: systemd.1
> Issue:    kernel command line twice?
>

Apparently this was fixed already.

> Man page: systemd-boot.7
> Issue:    enrollement → enrollment

Fixed.

> Man page: systemd-cryptenroll.1
> Issue:    multiple cases: any specified → the specified

Reworded.

> Issue:    If this this → If this

Fixed tree-wide.

> Man page: systemd-cryptsetup-generator.8
> Issue:    and the initrd → and in the initrd

"Is honoured by the initrd" is OK, because we often speak about the initrd as a single unit. But in the same paragraph we also used "in the initrd", which makes the other use look sloppy. I changed it to "in the initrd" everywhere in that file.

> Man page: systemd.directives.7
> Issue:    Why are these two quoted (but not others)?
>
> "B<\\*(Aqh\\*(Aq>"
>

This is autogenerated from files… We use slightly different markup in different files, and it's just too hard to make it consistent. We gave up on this.

> Man page: systemd.exec.5
> Issue 1:  B<at>(1p) → B<at>(1)
> Issue 2:  B<crontab>(1p) → B<crontab>(1)

Fixed.

> Man page: systemd.exec.5

Fixed.

> Man page: systemd.exec.5
> Issue:   qemu → B<qemu>(1)

The man page doesn't seem to be in any of the canonical places on the web.
I added a link to online docs.

> Man page: systemd.exec.5
> Issue:    variable → variables

Seems to be fixed already.

> Man page: systemd-integritysetup-generator.8
> Issue:    systemd-integritysetup-generator → B<systemd-integritysetup-generator>

I changed <filename> to <command>.

> Man page: systemd-integritysetup-generator.8
> Issue:    superfluous comma at the end

Already fixed.

> Man page: systemd-measure.1
> Issue:    (see B<--pcr-bank=>) below → (see B<--pcr-bank=> below)

Reworded.

> Man page: systemd-measure.1

Fixed.

> Man page: systemd-measure.1.po
> Issue:    B<--bank=DIGEST> → B<--bank=>I<DIGEST>

Fixed.

Appears to have been fixed already.

> Man page: systemd.netdev.5
> Issue:    Onboard → On-board (as in previous string)

Updated.

> Man page: systemd.network.5
> Issue:    B<systemd-networkd> -> B<systemd-networkd>(8)

First reference does this, subsequent do not.

> Man page: systemd.network.5
> Issue:    B<netlabelctl> → B<netlabelctl>(8)

First reference does this, subsequent do not.

> Man page: systemd.network.5
> Issue:    Missing verb (aquired? configured?) in the half sentence starting with "or by a "

I dropped the comma.

> Man page: systemd-nspawn.1
> Issue:    All host users outside of that range → All other host users

Reworded.

A period is added. Not sure if there's some other issue.

Done.

0ccfd3564b kernel-install: Add uki layout
Currently the kernel-install man page only documents the bls layout for use
with the boot loader spec type #1. 90-loaderentry.install uses this layout to
generate loader entries and copy the kernel image and initrd to $BOOT.

This commit documents a second layout "uki" and adds 90-uki-copy.install,
which copies a UKI "uki.efi" from the staging area or any file with the .efi
extension given on the command line to
$BOOT/EFI/Linux/$ENTRY_TOKEN-$KERNEl_VERSION(+$TRIES).efi

This allows for both locally generated and distro-provided UKIs to be handled
by kernel-install.

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.

This drops documentation of KERNEL_INSTALL_MACHINE_ID as machine-info

This updates the kernel-install man page to always say "ENTRY-TOKEN"

between the two.

367165a406 kernel-install: add "$KERNEL_INSTALL_STAGING_AREA" directory
The general approach of kernel-install was that each plugin would drop in some
files into the entry directory. But this doesn't scale well, because if we have
multiple initrd generators, or multiple initrds, each generator would need to
recreate the logic to put the generated files in the right place.

Also, effective cleanup is impossible if anything goes wrong on the way, so we
could end up with unused files in $BOOT.

So let's invert the process: plugins drop files into $KERNEL_INSTALL_STAGING_AREA,
and at the end 90-loaderentry.install DTRT with those files.

This allow new plugins like 50-mkosi-initrd.install to be significantly simpler.

5c1b257faf kernel-install: add new variable $KERNEL_INSTALL_INITRD_GENERATOR
The idea is that when not set, we do whatever we did in the past. But
with a new setting of initrd_generator=mkosi-initrd, mkosi-initrd will
generate an initrd.

641e2124de kernel-install: replace 00-entry-directory with K_I_LAYOUT in k-i
341890de86 made "bootctl install" create
ESP\MID, in preparation of cf73f65089 that
followed it and created 00-entry-directory.install to make ESP\MID\KVER
if ESP\MID existed ‒ this meant that "bootctl install" followed by
"kernel-install $(uname -r) /boot/vml*$(uname -r) /boot/ini*$(uname -r)"
actually installed the kernel correctly.

Later, 31e57550b5 reverted the first
commit, meaning, that now running those two commands first installs
sd-boot, but then does nothing. Everything appears to work right,
nothing errors out, but no changes are actually done. To the untrained
eye (all of them), even running with -v appears to work:
all the hooks are run, as is depmod, but, again, nothing happens.

This is horrible. Nothing in either manpage suggests what to do
(nor should it, really), but the user is left with a bootloader that
appears fully funxional, since nothing suggests a failure in the output,
but with an unbootable machine, /no way to boot it/, even if they drop
to an EFI shell, since the boot bundle isn't present on the ESP,
and no real recourse even if they boot into a recovery system,
apart from installing like GRUB or whatever.

00- is purely instrumentation for 90-,
and separating one from the other has led to downstream dissatisfaxion
(indeed, the last mentioned commit cited cited exactly that as the
 reversion reason), while creating $ENTRY_DIR_ABS is only required
for bootloaders using the BLS, and shouldn't itself toggle anything.

To that end, introduce an /{e,l}/k/install.conf file that allows
overriding the detected layout, and detect it as "bls" if
$BOOT_ROOT/$MACHINE_ID ($ENTRY_DIR_ABS/..) exists, otherwise "other" ‒
if a user wishes to select a different bootloader,
like GRUB, they (or, indeed, the postinst script) can specify
layout=grub. This disables 90- and $ENTRY_DIR_ABS manipulation.

357376d0bb kernel-install: Introduce KERNEL_INSTALL_MACHINE_ID in /etc/machine-info
If KERNEL_INSTALL_MACHINE_ID is defined in /etc/machine-info, prefer it
over the machine ID from /etc/machine-id. If a machine ID is defined in
neither /etc/machine-info nor in /etc/machine-id, generate a new UUID
and try to write it to /etc/machine-info as KERNEL_INSTALL_MACHINE_ID
and use it as the machine ID if writing it to /etc/machine-info succeeds.

In practice, this means we have a more robust fallback if there's no
machine ID in /etc/machine-id than just using "Default" and allows
image builders to force kernel-install to use KERNEL_INSTALL_MACHINE_ID
by simply writing it to /etc/machine-info themselves.
