Has the way cgroups and cgconfig work changed in el8 from el7?

I have this config file that works in el7: $ cat /etc/cgconfig.d/idle.conf # Configuration file generated by cgsnapshot group idle { perm { admin { uid = idle; gid = idle; } task { uid = idle; gid = idle; } } cpu { cpu.cfs_period_us="100000"; cpu.cfs_quota_us="-1"; cpu.shares="2"; } cpuacct { cpuacct.usage="0"; } }

Running cgconfig in el8 doesn't seem to restore it. Is this a known bug? Is additional configuration needed somewhere else?
