b1935cc943 tmpfiles: use dir_cleanup() for R and D
... i.e. apply nested config (exclusions and such) when executing R and D.

This fixes a long-standing RFE. The existing logic seems to have been an
accident of implementation. After all, if somebody specifies a config with
'R /foo; x /tmp/bar', then probably the goal is to remove stuff from under /foo,
but keep /tmp/bar. If they just wanted to nuke everything, then would not specify
the second item.

This also makes R and D use O_NOATIME, i.e. the access times of the directories
that are accessed will not be changed by the cleanup.

Obviously, we'll have to add this to NEWS and such.
Looking at the whole tmpfiles.d config in Fedora, this change has no effect.

The test cases are adjusted as appropriate. I also added another test case for
'R'/'D' with a file, just to test this code path more.

Replaces #20641.
Fixes #1633.

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.)

tmpfiles: add conditionalized execute bit (X) support
According to setfacl(1), "the character X stands for
the execute permission if the file is a directory
or already has execute permission for some user."

After this commit, parse_acl() would return 3 acl
objects. The newly-added acl_exec object contains
entries that are subject to conditionalized execute
bit mangling. In tmpfiles, we would iterate the acl_exec
object, check the permission of the target files,
and remove the execute bit if necessary.

Here's an example entry:
A /tmp/test - - - - u:test:rwX

Fixes #25780.

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
> Issue 1:  secure boot variables → Secure Boot variables

"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.

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

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>"
>
> B<\\*(Aqs\\*(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.

> # FIXME no effect → no effect\\&.
> #. type: Plain text

> msgid ""
> "Whichever ID mapping option is used, the same mapping will be used for users "

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)

Fixed.

> Man page: systemd-pcrphase.service.8

Fixed.

Fixed tree-wide.

Updated.

Looks all OK to me.

7f7a50dd15 tmpfiles: extend "Age" to accept an "age-by" argument
For "systemd-tmpfiles --cleanup", when the "Age" parameter
is specified, the criteria for deletion is determined from
the path's last modification timestamp ("mtime"), its last
access timestamp ("atime") and its last status change
timestamp ("ctime").

For instance, if one of those paths to be cleaned up are
opened, it results in the modification of "atime", which
results file system entry to not be removed because the
default aging algorithm would skip the entry.

Add an optional "age-by" argument by extending the "Age"
parameter to restrict the clean-up for a particular type
of file timestamp, which can be specified in "tmpfiles.d"
as follows:

  [age-by:]cleanup-age, where age-by is "[abcmACBM]+"

For example:

  d /foo/bar - - - abM:1m -

Would clean-up any files that were not accessed and created,
or directories that were not modified less than a minute ago
in "/foo/bar".

9a515f0a55 shared: add new IMAGE_VERSION=/IMAGE_ID= field to /etc/os-release
This specifes two new optional fields for /etc/os-release:
IMAGE_VERSION= and IMAGE_ID= that are supposed to identify the image of
the current booted system by name and version.

This is inspired by the versioning stuff in
https://github.com/systemd/mkosi/pull/683.

In environments where pre-built images are installed and updated as a
whole the existing os-release version/distro identifier are not
sufficient to describe the system's version, as they describe only the
distro an image is built from, but not the image itself, even if that
image is deployed many times on many systems, and even if that image
contains more resources than just the RPMs/DEBs.

In particular, "mkosi" is a tool for building disk images based on
distro RPMs with additional resources dropped in. The combination of all
of these together with their versions should also carry an identifier
and version, and that's what IMAGE_VERSION= and IMAGE_ID= is supposed to
be.

I actually think that not making the "argument" field accept quotes was
a mistake, but I also understand why this choice was made. Given that we
shipped this forever like this though I don't think it's worth changing
the behaviour now. Supporting quotes for this is not that important I
guess. Hence document the current behaviour.

f742f9d317 man: mention the exclamation mark and minus sign literally, to make things searchable
I was looking for the explanation for the exclamation mark in the text,
and couldn't find it, searching for "!". Let's make this easier, and
indicate the character meant.

e97708fa3e Add %l as specifier for the hostname without any domain component
As described in #15603, it is a fairly common setup to use a fqdn as the
configured hostname. But it is often convenient to use just the actual
hostname, i.e. until the first dot. This adds support in tmpfiles, sysusers,
and unit files for %l which expands to that.

Fixes #15603.

0d525a3e93 man: add specifiers section to directives index
The hack with getparent().txt is not very pretty, but the whole
thing seems to work well enough. It is useful to figure out whihc
specifiers are supported where.
