systemctl set-property user-1009.slice CPUQuota=50% 无法设置 user-1009.slice 的单元属性：单元 user-1009.slice 未加载

我正在尝试设置每个用户的进程限制，其中大多数都是使用 sudo --user 运行的。为什么我的系统上的 user-1001 和 user-1008 有切片文件，但我无法在 1009 上获取它？

# systemctl set-property user-1009.slice CPUQuota=50%
Failed to set unit properties on user-1009.slice: Unit user-1009.slice is not loaded.

# systemctl status user-1009.slice
● user-1009.slice
   Loaded: loaded
   Active: inactive (dead)

我尝试手动创建文件

# touch /etc/systemd/system/user-1009.slice

# systemctl status user-1009.slice
● user-1009.slice
   Loaded: masked (/etc/systemd/system/user-1009.slice; masked; vendor preset: disabled)
   Active: inactive (dead)

# systemctl set-property user-1009.slice CPUQuota=50%
Failed to set unit properties on user-1009.slice: Unit user-1009.slice is not loaded.

这对我来说也没有意义，测试进程（PID 26668）显示在 ps -U 1009 中，但它在用户 1008 的切片下运行（因为用户 1008 使用 sudo 来运行它？）

# ps -U 1009 ; systemctl status user-1008.slice
  PID TTY          TIME CMD
15727 pts/1    00:00:00 bash
26668 ?        00:00:00 testprocess
● user-1008.slice - User Slice of testuser

             └─26668 ./testprocess

四处搜索后，我发现人们都说要以用户身份登录才能解决这个问题，但显然该用户已经打开了进程。我尝试在另一个终端中使用 su - user1009，但似乎没有帮助

万一其他人需要解决方案，除了使用 sudo 之外，sudo systemd-run 对我来说也很有用

$ sudo systemd-run --uid=1009 --slice=user-1009 sleep 10

# ps -U 1009 ; systemctl status user-1009.slice

PID TTY TIME CMD

20199 ? 00:00:00 sleep

● user-1009.slice

Loaded: loaded

Active: active since Sun 2018-09-02 01:46:57 EDT; 2s ago

CGroup: /user.slice/user-1009.slice

      └─run-20198.service

        └─20199 /bin/sleep 10
