Feature Overview (aka. Goal Summary)  

Deprecated Cgroup v1 in 4.16 

4.16 is based on RHEL 9.4 and RHEL 9.4 is deprecating cgroup v1 . We want to maintain parity with RHEL 

"

cgroupsv1 is now deprecated in RHEL 9

The cgroups is a kernel subsystem used for process tracking, system resource allocation and partitioning. Systemd service manager supports booting in the cgroups v1 mode as well as in cgroups v2 mode. In Red Hat Enterprise Linux 9, the default mode is v2. In Red Hat Enterprise Linux 10, systemd will not support booting in the cgroups v1 mode and only cgroups v2 mode will be available."
