In general, it's not very usuful to repeat the unit name as the description.
Especially when the word is a common name and if somebody doesn't understand
the meaning immediately, they are not going to gain anything from the
repeat either, e.g. "halt", "swap".
In the status-unit-format=combined output parentheses are used around
Description, so avoid using parenthesis in the Description itself.

[ OK ] Created slice system-sshd\x2dkeygen.slice (Slice /system/sshd-keygen).
[ OK ] Created slice user.slice (User and Session Slice).
Before, the first three slices were shown without any description which didn't
look nice.
The code to print unit status formats had a long history, and became a
hard-to-manage mess of duplicate code parts. We would use sprintf() to
format a string, and then call sprintf() again… The code is reworked
to avoid repeated formattings and to streamline printing to the log
and the console.
The approach used in this patch is a bit more complex then in patches by Colin
Walter and Paweł Marciniak, because an allocation is only done if "combined"
format is used. In other cases we return the existing ->id or ->description
strings. The caller can also control whether a shorter or longer status string
should be used. This way the caller can use a shorter format where it makes
sense, for example in the cylon eye output, where we don't have enough
horizontal space.
Patch is based on Colin Walters' https://github.com/systemd/systemd/pull/15957,
and Paweł Marciniak's patch posted on fedora-devel.
Note: for some reason, the functions for printing of start and stop messages
were sepearated by some unrelated functions. They are moved to be consecutive,
but this makes the much more verbose than it would be otherwise. I found it
useful to view in gitk's "new" mode.

We checked the wrong field, which was always NULL here, so we would always
reject the assignment. We would also print the wrong string in the error
message:
$ sudo systemd-run --socket-property ListenFIFO=/tmp/fifo3 cat
Failed to start transient socket unit: Invalid socket path: FIFO
When an ExtensionImages= extension-release metadata does not match, the
log messages (unless debug level is set) are pretty much incomprehensible:
systemd[463]: run-u11.service: Failed to set up mount namespacing: /run/systemd/unit-extensions/0: Stale file handle
systemd[463]: run-u11.service: Failed at step NAMESPACE spawning /usr/bin/echo: Stale file handle
Add an explicit log message if we get ESTALE from the dissect code, to
make it clear what's happening without needing to enable debugging:
systemd[463]: Failed to mount image /tmp/app3.raw, extension-release metadata does not match the lower layer's: ID=debian VERSION_ID=11 SYSEXT_LEVEL=11
Only treat interface names containing dots specially when resolvectl is
pretending to be resolvconf to fix
https://github.com/systemd/systemd/issues/20014 .
Move the special suffix-stripping behaviour of ifname_mangle out to the
new ifname_resolvconf_mangle to be called from resolvconf only.
The mount option has special meaning when SELinux is enabled. To make
NoNewPrivileges=yes not break SELinux enabled systems, let's not set the
mount flag on such systems.
This reverts commit 1753d30215.
Let's re-enable that feature now. As reported when the original commit
was merged, this causes some trouble on SELinux enabled systems. So,
in the subsequent commit, the feature will be disabled when SELinux is enabled.
But, anyway, this commit just re-enable that feature unconditionally.
This fixes repart's, systemctl's, sysusers' and tmpfiles' specifier
expansion to honour the root dir specified with --root=. This is
relevant for specifiers such as %m, %o, … which are directly sourced
from files on disk.
This doesn't try to be overly smart: specifiers referring to runtime
concepts (i.e. boot ID, architecture, hostname) rather than files on the
medium are left as is. There's certainly a point to be made that they
should fail in case --root= is specified, but I am not entirely convinced
about that, and it's certainly something we can look into later if
there's reason to.
I wondered for a while how to hook this up best, but given that quite a
large number of specifiers resolve to data from files on disks, and most
of our tools needs this, I ultimately decided to make the root dir a
first class parameter to specifier_printf().
Replaces: #16187Fixes: #16183
Due to a little misunderstanding the last patch doesn't work as
expected, since test_create_image() is called only for the first image
(usually TEST-01-BASIC), and all subsequent images are then (possibly)
modified with test_append_files().
Follow-up to 179ca4d2b1.
If ActivationPolicy= is set to down, always-down, or manual, then any
matching link will delay boot (due to delaying network-online.target).
If RequiredForOnline= wasn't explicitly set, then default it to false
if ActivationPolicy= is down or manual. If ActivationPolicy=always-down,
then force RequiredForOnline=no.
We would always call path_simplify() before doing a lookup, which requires the
path key to be duplicated first. But the hashmap lookup doesn't require this…
So let's opportunistically skip the allocation if the key is already present.
Inspired by https://github.com/systemd/systemd/pull/19973.
The approach with function pointer was neat, but it gets in the way
when we want to resolve the symbol dynamically: static initialization
is not possible. It also makes the code more complicated than necessary.
In this case, a simple boolean is sufficient.
