…x,‰×ÿÀË ?÷ systemd System and Service Manager
CHANGES WITH 252 🎃:
Announcements of Future Feature Removals:
* We intend to remove cgroup v1 support from systemd release after the
end of 2023. If you run services that make explicit use of cgroup v1
features (i.e. the "legacy hierarchy" with separate hierarchies for
each controller), please implement compatibility with cgroup v2 (i.e.
the "unified hierarchy") sooner rather than later. Most of Linux
userspace has been ported over already.
* We intend to remove support for split-usr (/usr mounted separately
during boot) and unmerged-usr (parallel directories /bin and
/usr/bin, /lib and /usr/lib, etc). This will happen in the second
half of 2023, in the first release that falls into that time window.
For more details, see:

Compatibility Breaks:
* ConditionKernelVersion= checks that use the '=' or '!=' operators
will now do simple string comparisons (instead of version comparisons
á la stverscmp()). Version comparisons are still done for the
ordering operators '<', '>', '<=', '>='. Moreover, if no operator is
specified, a shell-style glob match is now done. This creates a minor
incompatibility compared to older systemd versions when the '*', '?',
'[', ']' characters are used, as these will now match as shell globs
instead of literally. Given that kernel version strings typically do
not include these characters we expect little breakage through this
change.
* The service manager will now read the SELinux label used for SELinux
access checks from the unit file at the time it loads the file.
Previously, the label would be read at the moment of the access
check, which was problematic since at that time the unit file might
already have been updated or removed.
New Features:
* systemd-measure is a new tool for calculating and signing expected
TPM2 PCR values for a given unified kernel image (UKI) booted via
sd-stub. The public key used for the signature and the signed
expected PCR information can be embedded inside the UKI. This
information can be extracted from the UKI by external tools and code
in the image itself and is made available to userspace i
