[Bulk] Re: confine user(s) to a core with systemd + gcgroup

[lejeczek]

hi, thanks for your input, however it does not help really
linked doc? I've thumb trough it before.

let me rephrase my question - how do I put users, their 
whole session from the moment they login into a cgroup cpuset?

and I don't want to use libcgroup (as it not recommended 
anyway) but have systemd managed it.

thanks
