|

sooner rather than later, if you haven't done so yet. Most of Linux
|
||||
userspace has been ported over already.
|
||||
|
||||
New features:
|
||||
|
||||
* systemd-measure is a new helper to precalculate PCR measurements
|
||||
to make it easier to set TPM2 policies.
|
||||
|
||||
Changes in systemd itself, i.e. the manager, and units
|
||||
|
||||
* The cpu controller is delegated to user manager units, and CPUWeight=
|
||||
settings are applied to the top-level user slice units (app.slice,
|
||||
background.slice, session.slice). This provides a degree of resource
|
||||
isolation between different user services competing for the CPU.
|
||||
|
||||
* Systemd can optionally do a full preset in the "first boot" condition
|
||||
(instead of just enable-only). This behaviour is controlled by the
|
||||
compile-time option -Dfirst-boot-full-preset=. Right now it defaults
|
||||
to 'false', but the plan is to switch it to 'true' for the subsequent
|
||||
release.
|
||||
|
||||
* Systemd will set the taint flag 'support-ended' if it detects that
|
||||
the os image is past its end-of-support date.
|
||||
|
||||
* Two new settings ConditionCredential= and AssertCredential= can
|
||||
be used to skip or fail units if a certain credential is not provided.
|
||||
|
||||
* ConditionMemory= accepts size suffixes.
|
||||
|
||||
* DefaultSmackProcessLabel= can be used in system.conf and user.conf
|
||||
to specify the smack label to use when not specified in a unit file.
|
||||
|
||||
* DefaultDeviceTimeoutSec= can be used system.conf and user.conf
|
||||
to specify the default timeout for devices.
|
||||
|
||||
* C.UTF-8 is used as the default locale if nothing else has been configured.
|
||||
|
||||
Changes in sd-boot, bootctl, and the Boot Loader Specification:
|
||||
|
||||
* The Boot Loader Specification has been cleaned up and clarified.
|
||||
Various corner cases in version string comparisons have been fixed
|
||||
(e.g. comparisons for empty strings). Boot counting is now part of
|
||||
the main specification.
|
||||
|
||||
* New PCRs measurements are set during boot: PCR 11 for the the
|
||||
kernel+initrd combo, PCR 13 for any sysext images.
|
||||
|
||||
* The UEFI monotonic boot counter is now included in the random seed,
|
||||
providing some additional entropy.
|
||||
|
||||
* Booting in EFI mixed mode (a 64-bit kernel over 32-bit UEFI firmware)
|
||||
is now supported.
|
||||
|
||||
* bootctl gained a bunch of new options: '--all-architectures' to
|
||||
install binaries for all supported EFI architectures, '--root=' and
|
||||
'--image=' options to operate on a directory or disk image, and
|
||||
'--install-source=' to specify the source for binaries to install.
|
||||
|
||||
* The sd-boot stub exports a StubFeatures flag, which is used by
|
||||
bootctl to show features supported by the stub that was used to boot.
|
||||
|
||||
Changes in the hardware database:
|
||||
|
||||
* 'systemd-hwdb query' now supports the '--root' option.
|
||||
|
||||
Changes in systemctl:
|
||||
|
||||
* systemctl now supports '--state' and '--type' options for the 'show'
|
||||
and 'status' verbs.
|
||||
|
||||
* systemctl gained a new verb 'list-automounts' to list automount
|
||||
points.
|
||||
|
||||
Changes in systemd-networkd:
|
||||
|
||||
* networkd can set Linux NetLabel labels for integration with the
|
||||
network control in security modules via a new NetLabel= option.
|
||||
|
||||
* networkd gained new options NFTSet=, IPv4NFTSet=, IPv6NFTSet= that
|
||||
take names of nft sets as arguments. It will automatically add rules
|
||||
for the subnets configured for an interface to those sets.
|
||||
|
||||
* The RapidCommit= is (re-)introduced to enable faster configuration
|
||||
via DHCPv6 (RFC 3315).
|
||||
|
||||
Changes in systemd-nspawn:
|
||||
|
||||
* The --bind= and --overlay= options now support relative paths.
|
||||
|
||||
Changes in libsystemd and other libraries:
|
||||
|
||||
* libsystemd now exports the sd-netlink interface that provides
|
||||
functions to send/receive/parse netlink and rtnl messages.
|
||||
|
||||
* libsystemd now exports sd_bus_error_setfv (a convenience function for
|
||||
setting bus errors), sd_id128_string_equal (a convenience function
|
||||
for identifier comparisons), sd_bus_message_read_strv_extend (a
|
||||
function to incrementally read string arrays).
|
||||
|
||||
* Private shared libraries (libsystemd-shared-nnn.so,
|
||||
libsystemd-core-nnn.so) are now installed into arch-specific
|
||||
directories to allow multi-arch installs.
|
||||
|
||||
Changes in other components:
|
||||
|
||||
* sysusers and tmpfiles configuration can now be provided via the
|
||||
credential mechanism.
|
||||
|
||||
* tmpfiles can read file contents to write from a credential (and a new
|
||||
modifier char '^' to specify that the argument is a credential name).
|
||||
This mechanism is used to automatically populate /etc/motd, /etc/issue,
|
||||
and /etc/hosts from credentials.
|
||||
|
||||
* systemd-analyze gained a new verb 'compare-versions' that implements
|
||||
comparisons for versions strings (similarly to 'rpmdev-vercmp' and
|
||||
'dpkg --compare-versions').
|
||||
|
||||
* The pkgconfig and rpm macros files now export the directory for user
|
||||
units as 'user_tmpfiles_dir' and '_user_tmpfilesdir'.
|
||||
|
||||
* Detection of Parallells and KubeVirt virtualization has been improved.
|
||||
|
||||
* os-release gained a new field SUPPORT_END=YYYY-MM-DD to inform the
|
||||
user when their system will become unsupported.
|
||||
|
||||
* When performing suspend-then-hibernate, the system will estimate the
|
||||
discharge rate and use that to set the delay until hibernation, and
|
||||
will hibernate immediately instead of suspending when running from a
|
||||
battery and the capacity is below 5%.
|
||||
|
||||
* systemd-sysctl gained a '--strict' option to fail when a sysctl
|
||||
setting is unknown to the kernel.
|
||||
|
||||
* machinectl supports '--force' for the 'copy-to' and 'copy-from'
|
||||
verbs.
|
||||
|
||||
* openssl is the default crypto backend for systemd-resolved. (gnutls
|
||||
is still supported.)
|
||||
|
||||
Experimental features:
|
||||
|
||||
* BPF programs can now be compiled with bpf-gcc.
|
||||
|
||||
* sd-boot can automatically enroll SecureBoot keys from files found on
|
||||
the ESP. This enrollment can be either automatic ('force' mode) or
|
||||
controlled by the user ('manual' mode).
