[systemd-devel] CPUQuota setting is not inherited from systemd slices

[Oliver Graute]

Hello,

I try to limit my CPUQuota for my dnt5411software.slice. But the
services in the slice do not inherit the CPUQuota=20% setting from the
dnt5411software.slice file. They still consume more then 20% of the
CPU.

Some clue whats wrong or missconfigured here? I'am using systemd 225
