[SOLVED] CPUset not working in Ubuntu 22.04

[Snoopy8]

Installed 22.04 with aim to try the native real time kernel.  However, unable to get CPUset running.  I tried using both SnakeOil and my own cset commands, but failed.

Using this command:
sudo cset shield -c 1-3
mount: /cpusets: none already mounted on /run/credentials/systemd-sysusers.service.
cset: **> mount of cpuset filesystem failed, do you have permission?

This thread discusses the issues, but it is beyond my knowledge and ability to fix.
