73e97bb064 man: use <simplelist> for file lists in synopsis
With <para><filename>…</filename></para>, we get a separate "paragraph" for
each line, i.e. entries separated by empty lines. This uses up a lot of space
and was only done because docbook makes it hard to insert a newline. In some
other places, <literallayout> was used, but then we cannot indent the source
text (because the whitespace would end up in the final page). We can get the
desired result with <simplelist>.

With <simplelist> the items are indented in roff output, but not in html
output. In some places this looks better then no indentation, and in others it
would probably be better to have no indent. But this is a minor issue and we
cannot control that.

(I didn't convert all spots. There's a bunch of other man pages which have two
lines, e.g. an executable and service file, and it doesn't matter there so
much.)

607343a1ac repart: add new --copy-source= switch
This specifies a directory to which CopyFiles= is considered relative.
If unset defaults to the --root=/--image= setting, or host / otherwise.

This is very similar to --root= but is much more focussed: it is really
and exclusively about CopyFiles= (and related settings such as
ExcludeFiles=) and does not affect any of the settings, i.e. it doesn't
affect CopyBlocks=, the machine ID/seed handling, or where definitions
are read from.

In fact, --root= and --copy-source= may be combined for example to
use the machine ID and similar from one tree, but the copy the files
from another.

This tries to add information about when each option was added. It goes

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.

dea0dc7ba2 repart: Allow combining CopyBlocks= and CopyFiles=
Let's allow the combination of these two options. When used, repart
will first try to apply the CopyBlocks= behavior. If that's not possible,
it falls back to the CopyFiles= behavior.

This is a first step in being able to also use the partition definition
files shipped in the image to build the image in mkosi instead of having
a separate set of repart definition files to build the image.

600bf76c17 repart: Allow target directory excludes
Currently, ExcludeFiles= supports excluding directories on the host
from being copied. Let's extend this to also support preventing files
from being copied into specific directories in the partition by adding
a new option ExcludeFilesTarget=. An example where this is useful is
when setting up btrfs subvolumes in the top level that are intended to
be mounted into specific locations, so /usr would be stored in @usr,
/home in @home, .... To accomplish this, we need to copy /usr to @usr
and prevent any files from being copied into /usr in the partition,
which with this commit, we'd be able to do as follows:

```
[Partition]
CopyFiles=/usr:@usr
ExcludeFilesTarget=/usr
```

b63bd125d4 copy: Support both inode exclusion and contents exclusion
In some cases, we want to exclude a directory's contents but not
the directory itself. In other cases, we want to exclude a directory
and its contents. Let's extend the denylist logic in copy.h to support
both by changing the denylist from a set to hashmap so we can store the
deny type as the value.

We also modify the repart ExcludeFiles= option to make use of this. If
a directory to exclude ends with a "/", we'll only exclude its contents.
Otherwise, we'll exclude the full directory.

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.

Same.

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

> Man page: kernel-install.8

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

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

> Man page: loader.conf.5

Fixed.

> Man page: logind.conf.5

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

The first reference does this, subsequent are shorter.

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.

Apparently this was fixed already.

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

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

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

> Issue:    variable → variables

Seems to be fixed already.

> Man page: systemd-integritysetup-generator.8

I changed <filename> to <command>.

> Man page: systemd-integritysetup-generator.8

Already fixed.

Appears to have been fixed already.

Updated.

> Man page: systemd.network.5

First reference does this, subsequent do not.

First reference does this, subsequent do not.

> Man page: systemd.network.5

I dropped the comma.

> Man page: systemd-nspawn.1

Reworded.

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

Done.

5c33b68652 repart: Rework Minimize= option settings
Instead of having Minimize= take a boolean let's allow for two
different ways to enable it. "best" means we want the most minimal
image possible, which currently is only possible for read-only
filesystems but can be extended in the future with bisection
to find the most minimal possible size.

We also add "guess", which is the current behavior, where we
populate once and use the sparse size to make a reasonable guess
on a size that fits all the sources without needing to O(log(n))
tries to find the most minimal size.

09e917ea4d repart: support erofs
So, i think "erofs" is probably the better, more modern alternative to
"squashfs". Many of the benefits don't matter too much to us I guess,
but there's one thing that stands out: erofs has a UUID in the
superblock, squashfs has not. Having an UUID in the superblock matters
if the file systems are used in an overlayfs stack, as overlayfs uses
the UUIDs to robustly and persistently reference inodes on layers in
case of metadata copy-up.

Since we probably want to allow such uses in overlayfs as emplyoed by
sysext (and the future syscfg) we probably should ramp up our erofs game
early on. Hence let's natively support erofs, test it, and in fact
mention it in the docs before squashfs even.

4cee83331c repart: Add --split option to generate split artifacts
For use with sysupdate or other systemd tooling, it's useful to be
able to generate split artifacts from disk images, where each
partition is written to a separate file. Let's support this with
a --split switch for repart and a SplitName= configuration option.

--split enables split artifacts generation, and SplitName= configures
for which partition to generate split artifacts, and which suffix to
add to the split artifact name.

For SplitName=, we add support for some extra specifiers, more specifically
the partition Type UUID and the partition UUID.

b5b7879a5d repart: Add support for formatting verity partitions
This commit adds a new Verity= setting to repart definition files
with two possible values: "data" and "hash".

If Verity= is set to "data", repart works as before, and populates
the partition with the content from CopyBlocks= or CopyFiles=.

If Verity= is set to "hash", repart will try to find a matching
data partition with Verity=data and equal values for CopyBlocks=
or CopyFiles=, Format= and MakeDirectories=. If a matching data
partition is found, repart will generate verity hashes for that
data partition in the verity partition. The UUID of the data
partition is set to the first 128 bits of the verity root hash. The
UUID of the hashes partition is set to the final 128 bits of the
verity root hash.

ff0771bfc8 repart: make No-Auto GPT partition flag configurable too
This is useful for provisioning initially empty secondary A/B root file
systems. We don't want those to ever be considered for automatic
mounting, for example in "systemd-nspawn --image=", hence we should
create them with the No-Auto flag turned on. Once a file system image is
dropped into the partition the flag may be turned off by the updater
tool, so that it is considered from then on.

Thew new option for this is called NoAuto. I dislike negated options
like this, but this is taken from the naming in the spec, which in turn
inherited the name from the same flag for Microsoft Data Partitions. To
minimize confusion, let's stick to the name hence.

b3e22322b6 repart: resolve $TMP specifiers too
This might be useful for CopyFiles=, to reference some subdir of $TMP in
a generic way. This allows us to use the new common
system_and_tmp_specifier_table[].

1c41c1dc34 repart: add GrowFileSystem= setting to set new GPT partition flag for newly created partitions
And set it to on by default, except if partition is marked read-only.

e73309c532 repart: add new ReadOnly= and Flags= settings for repart dropins
Let's make the GPT partition flags configurable when creating new
partitions. This is primarily useful for the read-only flag (which we
want to set for verity enabled partitions).

This adds two settings for this: Flags= and ReadOnly=, which strictly
speaking are redundant. The main reason to have both is that usually the
ReadOnly= setting is the one wants to control, and it' more generic.
Moreover we might later on introduce inherting of flags from CopyBlocks=
partitions, where one might want to control most flags as is except for
the RO flag and similar, hence let's keep them separate.

5c08da586f repart: add CopyBlocks=auto support
When using systemd-repart as an installer that replicates the install
medium on another medium it is useful to reference the root
partition/usr partition or verity data that is currently booted, in
particular in A/B scenarios where we have two copies and want to
reference the one we currently use. Let's add a CopyBlocks=auto for this
case: for a partition that uses that we'll copy a suitable partition
from the host.

CopyBlocks=auto finds the partition to copy like this: based on the
configured partition type uuid we determine the usual mount point (i.e.
for the /usr partition type we determine /usr/, and so on). We then
figure out the block device behind that path, through dm-verity and
dm-crypt if necessary. Finally, we compare the partition type uuid of
the partition found that way with the one we are supposed to fill and
only use it if it matches (the latter is primarily important on
dm-verity setups where a volume is likely backed by two partitions and
we need to find the right one).

This is particularly fun to use in conjunction with --image= (where
we'll restrict the device search onto the specify device, for security
reasons), as this allows "duplicating" an image like this:

    # systemd-repart --image=source.raw --empty=create --size=auto target.raw

If the right repart data is embedded into "source.raw" this will be able
to create and initialize a partition table on target.raw that carrries
all needed partitions, and will stream the source's file systems onto it
as configured.
