systemd does not expose this currently, even though we'd love to. This
depends on the cpuset cgroup controller in the kernel becoming usable
however, it currently is really broken conceptually on cgroupsv1, and
on cgroupsv2 currently doesn't exist at all...

So yeah, "taskset" is the only way right now.
