Package: systemd Version: 241-7~deb10u2 Severity: normal Dear Maintainer,
I have a service with: [Service] ControlGroupAttribute=memory.swappiness 0 But when I look at the process's entry in /sys/fs/cgroup/memory/system.slice/servicename.service/memory.swappiness I see it has the default swappiness of 60. What's more is that I can't do this: ExecStartPost=/bin/sh -c "echo 0 > /sys/fs/cgroup/memory/system.slice/ servicename.service/memory.swappiness" because ExecStartPost is apparently run before the cgroup is established. This is really awful behavior because I can't spawn essential services that rely on not getting swapped out on my very busy server. This deeply affects performance of my servers.
