running services in a race-free manner, and in particular collect
information about exit statuses and results.
* The nss-resolve module has been changed to strictly return UNAVAIL
when communication via D-Bus with resolved failed, and NOTFOUND when
a lookup completed but was negative. This means it is now possible to
neatly configure fallbacks using nsswitch.conf result checking
expressions. Taking benefit of this, the new recommended
configuration line for the "hosts" entry in /etc/nsswitch.conf is:
hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname
* A new setting CtrlAltDelBurstAction= has been added to
/etc/systemd/system.conf which may be used to configure the precise
behaviour if the user on the console presses Ctrl-Alt-Del more often
than 7 times in 2s. Previously this would unconditionally result in
an expedited, immediate reboot. With this new setting the precise
operation may be configured in more detail, and also turned off
entirely.
* In .netdev files two new settings RemoteChecksumTx= and
RemoteChecksumRx= are now understood that permit configuring the
remote checksumming logic for VXLAN networks.
* The service manager learnt a new "invocation ID" concept for invoked
services. Each runtime cycle of a service will get a new invocation
ID (a 128bit random UUID) assigned that identifies the current
run of the service uniquely and globally. A new invocation ID
is generated each time a service starts up. The journal will store
the invocation ID of a service along with any logged messages, thus
making the invocation ID useful for matching the online runtime of a
service with the offline log data it generated in a safe way without
relying on synchronized timestamps. In many ways this new service
invocation ID concept is similar to the kernel's boot ID concept that
uniquely and globally identifies the runtime of each boot. The
invocation ID of a service is passed to the service itself via an
environment variable ($INVOCATION_ID). A new bus call
GetUnitByInvocationID() has been added that is similar to GetUnit()
but instead of retrieving the bus path for a unit by its name
retrieves it by its invocation ID. The returned path is valid only as
long as the passed invocation ID is current.
* systemd-resolved gained a new "DNSStubListener" setting in
resolved.conf. It either takes a boolean value or the special values
"udp" and "tcp", and configures whether to enable the stub DNS
listener on 127.0.0.53:53.
* IP addresses configured via networkd may now carry additional
configuration settings supported by the kernel. New options include:
HomeAddress=, DuplicateAddressDetection=, ManageTemporaryAddress=,
PrefixRoute=, AutoJoin=.
* The PAM configuration fragment file for "user@.service" shipped with
systemd (i.e. the --user instance of systemd) has been stripped to
the minimum necessary to make the system boot. Previously, it
contained Fedora-specific stanzas that did not apply to other
distributions. It is expected that downstream distributions add
additional configuration lines, matching their needs to this file,
using it only as rough template of what systemd itself needs. Note
that this reduced fragment does not even include an invocation of
pam_limits which most distributions probably want to add, even though
systemd itself does not need it. (There's also the new build time
option --with-pamconfdir=no to disable installation of the PAM
fragment entirely.)
* If PrivateDevices=yes is set for a service the CAP_SYS_RAWIO
capability is now also dropped from its set (in addition to
CAP_SYS_MKNOD as before).
* In service unit files it is now possible to connect a specific named
file descriptor with stdin/stdout/stdout of an executed service. The
name may be specified in matching .socket units using the
FileDescriptorName= setting.
* A number of journal settings may now be configured on the kernel
command line. Specifically, the following options are now understood:
systemd.journald.max_level_console=,
systemd.journald.max_level_store=,
systemd.journald.max_level_syslog=, systemd.journald.max_level_kmsg=,
systemd.journald.max_level_wall=.
* "systemctl is-enabled --full" will now show by which symlinks a unit
file is enabled in the unit dependency tree.
