Delegation of controllers to less privileges containers is not safe, and we don't support that right now either. Sorry.

[systemd-devel] Adding controllers
Hi, I tried to look for information but could not get any. I have created a systemd unit which runs systemd-nspawn of my local ubuntu rootfs. The unit has values to restrict cpu, memory etc., [Unit] Description=ubuntu After=network.target [Service] Type=simple ExecStart=/usr/bin/systemd-nspawn --keep-unit -jbD /machines/ubuntu CPUAcounting=yes MemoryAccouting=yes CPUShares=200 MemorySwapMax=1M MemoryMax=1073741824 MemoryLimit=1073741824 CPUQuota=50% TasksMax=100 [Install] WantedBy=multi-user.target [Manager] JoinControllers= --- From what I can read from the man page, The joincontrollers is a list of controllers the systemd unit will "not" join.. Please correct me if my understanding is wrong. I am however not able to make this systemd-nspawn join freezer controller. The only way I am able to achieve this is ExecStart=/usr/bin/cgexec -g freezer:/ubuntu /usr/bin/systemd-nspawn --keep-unit -jbD /machines/ubuntu (of course I use ExecStartPre to create the freezer:/ubuntu) But I feel there must be more systemd-native elegant way to do this. Please can someone guide me ? thanks Bhasker ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
