When using --root=/--image= the binaries to install/update will be
picked from the directory/image. Add an option to let the caller
choose.
By default (auto) the image is tried first, and if nothing is found
then the host. The other options allow to strictly try the image
or host and ignore the other.
GIT_VERSION is not available as a config.h variable, because it's rendered
into version.h during builds. Let's rework jinja2 rendering to also
parse version.h. No functional change, the new variable is so far unused.
I guess this will make partial rebuilds a bit slower, but it's useful
to be able to use the full version string.
systemd-udev-trigger.service by default triggeres all devices regardless
of whether they were already recognized by systemd-udevd.
There are machines (especially in embedded environments) where
systemd-udev-trigger.service is configured to run at a later stage of
the boot sequence, which can lead to quite a lot of devices being
triggered although they were already recognized by systemd-udevd.
Re-triggering a lot of devices is a relatively expensive operation and
therefore should be avoided if unnecessary.
Therefore this patch introduces --initialized-nomatch, which filters out
devices that are already present in the udev database. For consistance
reasons --initialized-match is implemented as well, which filters out devices
that are *not* already present in the udev database.
Replaces #19949.
This patch changes busctl capture to generate pcapng format
instead of the legacy pcap format files. It includes basic
meta-data in the file and still uses microsecond time
resolution. In future, more things can be added such as
high resolution timestams, statistics, etc.
PCAP Next Generation capture file format is what tshark uses
and is in process of being standardized in IETF. It is also
readable with libpcap.

systemd-analyze critical-chain accepts an optional unit argument,
however currently there's no shell-completion for it
This change provides unit name completion for both bash and zsh.
Closes: #20927
Allows to pass a portable profile when doing offline analysis of
units. Especially useful for analyzing portable images, since a
lot of the security-relevant settings in those cases come from
the profiles, but they are not shipped in the portable images.
