Is it planned? Note that CPUAffinity= uses the mechanism of sched_setaffinity(2) which is different from using cpuset controller restrictions (that's also why you find it in `man systemd.exec` and not it `man systemd.resource-control`).
IMO, systemd may eventually support the cpuset controller with a different directive. > [...] on the RHEL7 both libvirt & kubernetes handle its vm & pods in > kubepods.slice and machine.slice sub cgroup respectively in > appropriate cpuset mount point. [...] The components that do CPU pinning via cpuset controller do that on their own (relying on no collisions in the cpuset tree). Michal
