I am attempting to run Podman on my device and containers fail with a CGroup warning.
After some troubleshooting, I have determined that the issue appears to be related to setting the CPUSET controller.
root@OpenWrt:~# cat /sys/fs/cgroup/cgroup.controllers
cpuset cpu io memory pids rdma
root@OpenWrt:~# echo "+cpuset" > /sys/fs/cgroup/cgroup.subtree_control
ash: write error: Invalid argument
Open issues for reference.
