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.

kernel-install: replace 00-entry-directory with K_I_LAYOUT in k-i
341890de866f2ee34919a47ce3fc6c8cd3c1924c made "bootctl install" create
ESP\MID, in preparation of cf73f650890b56a59bfb713c4c82b4e29daa7316 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, 31e57550b552e113bd3d44355b237c41e42beb58 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.

kernel-install: replace 00-entry-directory with K_I_LAYOUT in k-i
341890de866f2ee34919a47ce3fc6c8cd3c1924c made "bootctl install" create
ESP\MID, in preparation of cf73f650890b56a59bfb713c4c82b4e29daa7316 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, 31e57550b552e113bd3d44355b237c41e42beb58 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.

<para>Using the machine ID for naming the entries is generally preferable, however there are cases

where using the other identifiers is a good option. Specifically: if the identification data that

|
|
the machine ID entails shall not be stored on the (unencrypted) <varname>$BOOT_ROOT</varname>
|
|
|
|
|
partition, or if the ID shall be generated on first boot and is not known when the entries are
|
|
|
|
|
prepared. Note that using the machine ID has the benefit that multiple parallel installations of
|
|
|
|
|
the same OS can coexist on the same medium, and they can update their boot loader entries
|
|
|
|
|
independently. When using another identifier (such as the OS ID or the OS image ID), parallel
|
|
|
|
|
installations of the same OS would try to use the same entry name. To support parallel
|
|
|
|
|
installations, the installer must use a different entry token when adding a second installation.

man: fix issues reported by the manpage-l10n project
Fixes #25780.

> "I<cipher=>, I<hash=>, I<size=>"
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

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
> Issue 1: secure boot variables → Secure Boot variables
> Issue 2: one → one for (multiple times)
>
> "Supported secure boot variables are one database for authorized images, one "
> "key exchange key (KEK) and one platform key (PK)\\&. For more information, "

"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
> Issue: Portable Services → Portable Services Documentation?
Updated.
> Man page: pam_systemd_home.8
> Issue: auth and account use "reason", while session and password do not?
Reworded.
> Man page: portablectl.1
> Issue: In systemd-portabled.service(8): Portable Services Documentation
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?
>
> "Takes a boolean argument\\&. If false disables importing credentials from "
> "the kernel command line, qemu_fw_cfg subsystem or the kernel command line\\&."
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.
> Man page: systemd-cryptenroll.1
> 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>"
>
> B<\\*(Aqs\\*(Aq>"
>
> "B<\\*(Aqy\\*(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
> Issue: B<select()> → B<select>(2)
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
> Issue: =PATH> → =>I<PATH>
Fixed.
> Man page: systemd-measure.1.po
> Issue: B<--bank=DIGEST> → B<--bank=>I<DIGEST>
Fixed.
> Man page: systemd.netdev.5
> Issue: os the → on the
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.
> # FIXME no effect → no effect\\&.
> #. type: Plain text
> #: archlinux debian-unstable fedora-rawhide mageia-cauldron opensuse-tumbleweed
> msgid ""
> "Whichever ID mapping option is used, the same mapping will be used for users "
> "and groups IDs\\&. If B<rootidmap> is used, the group owning the bind "
> "mounted directory will have no effect"
A period is added. Not sure if there's some other issue.
> Man page: systemd-oomd.service.8
> Issue: B<systemd> → B<systemd>(1)
Done.
> Man page: systemd.path.5
> Issue 1: B<systemd.exec>(1) → B<systemd.exec>(5)
> Issue 2: This section does not (yet?) exist
Fixed.
> Man page: systemd-pcrphase.service.8
> Issue 1: indicate phases into TPM2 PCR 11 ??
> Issue 2: Colon at the end of the paragraph?
Fixed.
> Man page: systemd-pcrphase.service.8
> Issue: final boot phase → final shutdown phase?
Updated.
> Man page: systemd-pcrphase.service.8
> Issue: for the the → for the
Fixed tree-wide.
> Man page: systemd-portabled.service.8
> Issue: In systemd-portabled.service(8): Portable Services Documentation
Updated.
> Man page: systemd-pstore.service.8
> Issue: Here and the following paragraphs: . → \\&. // Upstream: What does this comment mean? // You normally write \\&. for a full dot (full stop etc.); here you write only "." (i.e. a plain dot).

Looks all OK to me.
> Man page: systemd.resource-control.5
> Issue: Missing closing bracket after link to Control Groups version 1
Fixed.
> Man page: systemd-sysext.8
> Issue: In systemd-portabled.service(8): Portable Services Documentation
Updated.
> Man page: systemd.timer.5

Updated.

Fixed.

Updated.

Updated.
> Man page: sysupdate.d.5

"image" seems correct.
> Man page: tmpfiles.d.5

the machine ID, i.e. same as <varname>$KERNEL_INSTALL_MACHINE_ID</varname>, but might also be a

different type of identifier, for example a fixed string or the <varname>ID=</varname>,

entry token to use is read from <filename>/etc/kernel/entry-token</filename>, if it exists. Otherwise a

|
|
|
|
few possible candidates below <varname>$BOOT</varname> are checked for Boot Loader Specification Type 1

kernel-install: replace 00-entry-directory with K_I_LAYOUT in k-i
341890de866f2ee34919a47ce3fc6c8cd3c1924c made "bootctl install" create
ESP\MID, in preparation of cf73f650890b56a59bfb713c4c82b4e29daa7316 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, 31e57550b552e113bd3d44355b237c41e42beb58 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.
