Nope.

The perms logic for this hasn't been hashed out with Tejun yet. What I'd
like to see is that we can open up certain "safe" cgroup props for
unpriviliged systemd instances, like the ones for CPU shares. But this
hasn't been hashed out in all detail yet. For now, cgroup resource
control is only really available for system services.
