In this mode, we'll directly connect stdin/stdout/stderr of the invoked
service with whatever systemd-run itself is invoked on. This allows
inclusion of "systemd-run" commands in shell pipelines, as unlike
"--pty" this means EOF of stdin/stdout/stderr are propagated
independently.
If --pty and --pipe are combined systemd-run will automatically pick the
right choice for the context it is invoked in, i.e. --pty when invoked
on a TTY, and --pipe otherwise.
In libudev (which es much older code than the rest of systemd), we
propagate errors in functions not returning an int, via (positive) errno
(i.e. libc-style), and as negative Exyz values in those returning an int
(much preferred, i.e. Linux kernel style). Let's fix up a few place,
where this was incorrectly done, or not done at all.
Fixes: #6613
The values for StartLimitAction are defined in `man systemd.unit`.
Don't send people to `man systemd.service` just to find they need to look
back in `man systemd.unit` again :).
in other way we will get a warning message:
../src/core/kmod-setup.c:83:13: warning: ‘has_virtio_rng’ defined but
not used [-Wunused-function]
static bool has_virtio_rng(void) {
^~~~~~~~~~~~~~
If dbus is already down during shutdown, we can't propagate the cgroup
release message anymore, but that's expected and nothing to warn about.
Hence let's downgrade the message from LOG_WARN to LOG_DEBUG.
Fixes: #6777
glibc appears to propagate different errors in different ways, let's fix
this up, so that our own code doesn't get confused by this.
See #6752 + #6737 for details.
Fixes: #6755
Trying to connect otherwise is pointless, because if socket isn't around
we won't connect. However, when dbus.socket is present we attempt to
connect. That attempt can't succeed because we are then supposed
to activate dbus.service as a response to connection from
us. This results in deadlock.
Fixes#6303
'journalctl --vacuum-*' does not suppress output message with --quiet.
Let journal_directory_vacuum honors --quiet to fix the problem.

They’re counterparts to the existing set-log-level and set-log-target
verbs, simply printing the current value to stdout. This makes it
slightly easier to temporarily change the log level and/or target and
then restore the old value(s).
assemble multidevice btrfs volumes without external tools
This self-contained approach introduce very little overhead, unless
someone has a large number of devices composing many btrfs volumes,
in which case btrfs device scan would be faster. Still, having robust
implementation is a nice to have alternative for btrfs-progs.
Add prefix delegation documentation covering IPv6PrefixDelegation=
setting in the Network section as well as all the parameters and
the IPv6PrefixDelegation and IPv6Prefix sections implemented so
far, including DNS= and DNSLifetimeSec= settings.
Parse DNS IPv6 addresses and DNS server lifetime from .network files
so that they can be included in Router Advertisement RDNSS options.
RDNSS address and lifetime information is added to the
[IPv6PrefixDelegation] section according to the following syntax:
DNS=2001:db8:🅰️b 2001:db8::c:d
DNSLifetimeSec=1042
to initialize Network variables when Anonymize is true.
* do not send hostname
* client identifier set to MAC
* do not send vendor class identifier
* do not send other PRL options
