CHANGES WITH 253 in spe:
+ Announcements of Future Feature Removals and Incompatible Changes:
+
+ * 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:
+ https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html
+
Deprecations and incompatible changes:
* systemctl will now warn when invoked without /proc/ mounted
