Previously, ONCE is false for the first time, and true for later times,
hence log_once() and log_once_errno() suppress logging in the first call,
rather than later calls.
Fortunately, ONCE macro is only used in log_once() and log_once_errno(),
hence this only fixes spurious logging.
This should allow us to get rid of a bunch of "fail:" labels, because we
can clean up tmpfiles relative to some atfd this way.
This only ports over a small number of potential users, but there's more
work to be done.
This doesn't work anymore, setting it to false still makes
udev link to libsystemd-shared, as an argument was mistakenly
dropped.

"path" sounds like a fully qualified complete string referencing some
terminal object. But here it's not like that, the field just stores the
directory the object we actually care about is placed in. Hence let's
change this field to be named "directory", to be less confusing for
readers.
Some distributions does not have man package, but named man-db or so,
and most distribution specific mkosi.conf files already have them.
Let's drop man from the global config.
The function searches the list, and it potentially takes O(n).
Let's cache the result and avoid duplicated calls.
This also rebreaks comments, and rewrites conditions in an equivalent
form that is easy to read and matches with the comment above.
No functional change, just refactoring.
This PR implements what is proposed in
https://github.com/systemd/systemd/issues/37992.
Having a global config file that supports the same cmdline options for
sysext/confext allows the user to customize the behavior of
systemd-sysext.service unit too, without the need of hacking the service
manually.
The global config will live in
`CONF_PATHS_STRV()/systemd/{sysext/confext}.conf` and it will be
overridden by cmdline, so it is possible to customize a run if
`systemd-sysext` is executed manually.
For now support `--mutable=` (`Mutable`) and `--image-policy=`
(`ImagePolicy`).
Enhance CPU time logging to include wall clock duration alongside
CPU consumption. When a unit transitions to inactive/failed state,
the log message now shows both CPU time consumed and the total wall
clock time since activation.
Changes:
- Calculate wall clock duration using active_enter_timestamp
- Update log format: "Consumed Xs CPU time over Ys wall clock time"
- Fallback to original format if no activation timestamp available
- Use monotonic clock for accurate duration calculation
This addresses issue #35738 by providing administrators better context
about service performance and resource efficiency.
Example output:
- With wall clock: "service: Consumed 30s CPU time over 5min wall clock time"
- Without timestamp: "service: Consumed 30s CPU time"
Container managers may want to bind mount the root filesystem
somewhere within the container. Security-wise, this is very much not
recommended, but it may be something application containers may want
to do nonetheless.

We only support a subset of filesystems, and no RAID, for DDIs. blkid spends a lot
of time trying to probe for the filesystem type, so cut it short by using
the filtering options to restrict it to the filesystems we support, and to
exclude raid probing.
The code was of two minds about error_id: it was used directly in
pam_syslog_errno(), but in the next line checked with streq_ptr().
sd_varlink_callbo() may return negative and then it does not set the output
params, or it returns the error in ret_error_id. We cannot assume that error_id
is non-null. Also fix a select-and-paste mistake in one place.

[ 6.570846] systemd-journald[251]: Too many messages being logged to kmsg, ignoring
The error message was misleading, since it sounds like there's an issue with
symlinks, but the device simply doesn't exist. But I think we should suppress
the message altogether. journald spewing messages like this fills up the logs
for no benefit. The sd_device_new* functions can legitimately be used for
"invalid" devices, e.g. to check if they even exist. We have no idea for what
purpose the caller is creating the device object, so let's not log this at all.
The caller can log if appropriate.
For file:// there's no http error code 404, but there's
CURLE_FILE_COULDNT_READ_FILE hence call ->on_not_found() in that case
too.

I noticed in our NixOS packaging that we were working around the fact
that core/swap.c looks for swapon and swapoff in /sbin
Lets make it configurable just like all the other util-linux binaries
through meson and make it default to /usr/sbin/{swapon,swapoff}
This way mounts work on a systemd without the /sbin -> /usr/sbin
compatibility symlink. (And as a side-effect has NixOS be able to have
it in /nix/store too like the other util-linux tools).
Given that `unmerged-usr` support was dropped in 255 I think this is a
safe change?
path_is_root_at() is supposed to detect if the inode referenced by the
specified fd is the "root inode". For that it checks if the inode and
its parent are the same inode and the same mount. Traditionally this
check was correct. But these days we actually have detached mounts (i.e.
those returned by fsmount() and related calls), whose root inode also
behaves like that.
Our uses for path_is_root_at() use the function to detect if an absolute
path would be identical to a relative path based on the specified fd
(sepifically: chaseat()), which goes really wrong if used on a detached
mount.
hence, let's adjust the function a bit, and let's go by path to "/" to
check if the referenced inode is the actual root inode in our chroot.
Commit d7bea6b6 ("nspawn: introduce an option for specifying network
namespace path") already did most of the work here enabling a command
line option for specifying the namespace path for a given container.
Someone even took care of the merging code in merge_settings as though
this already worked. All that's then needed is to add a line to the
nspawn-gperf.gperf file to actually enable being able to specify
NamespacePath from nspawn files as well.
This greatly simplifies how we configure nspawn containers by being able
to give all the options we need in .nspawn files instead of needing to
also use command line parameters.
Closes: #27188
These images are not using a passphrase, they are using keys
or at most TPM-based sealing (not yet implemented, for contexts).
Do not use the interactive helper, as it will block and ask the
user for a password if it fails to find the signing cert, which
is not useful for this tool.
