      * Previously, when restarting a {sno} cluster with a performance profile applied, a race condition caused systemd processes to remain in the root directory instead of being moved to `/sys/fs/cgroup/cpuset/system.slice`. With this release, systemd processes are moved to `/sys/fs/cgroup/cpuset/system.slice` as expected following a {sno} node restart.

      This is a clone of issue OCPBUGS-30569. The following is the description of the original issue:

      Description of problem:

      This is only applicable to systems that install a performance profile
      
      There seems to be a race condition where all systemd spawed processes are not being moved to /sys/fs/cgroup/cpuset/system.slice.
      
      This is suppose to be done by the one-shot cpuset-configure.service. 
      Here is a list of processes I see on one lab that are still in the root directory 
      
      /usr/bin/dbus-broker-launch --scope system --audit
      dbus-broker --log 4 --controller 9 --machine-id 071fd738af0146859d2c04b7fea6d276 --max-bytes 536870912 --max-fds 4096 --max-matches 131072 --audit
      /usr/sbin/NetworkManager --no-daemon
      /usr/sbin/dnsmasq -k
      /sbin/agetty -o -p -- \u --noclear - linux
      sshd: core@pts/0
      
      
      

      Version-Release number of selected component (if applicable):

          4.14, 4.15

      How reproducible:

          

      Steps to Reproduce:

          1. Reboot a SNO with a peformance profile applied 
          2.
          3.
          

      Actual results:

          

      Expected results:
