udev 在重启后不会自动加载规则

我有一条规则应该应用于/dev/ipmi0更改其组和模式。当我重新启动时，该节点显示为 root:root，但如果我运行“测试”，它会成功应用它：

$ cat /etc/udev/rules.d/99-ipmi-nonroot.rules
SUBSYSTEM=="ipmi", KERNEL=="ipmi0", GROUP="adm", MODE="0660"

$ ls -l /dev/ipmi*
crw------- 1 root root 244, 0 Jul  6 16:57 /dev/ipmi0

$ sudo udevadm test /sys/class/ipmi/ipmi0
....

...

$ ls -l /dev/ipmi*
crw-rw---- 1 root adm 244, 0 Jul  6 17:00 /dev/ipmi0

我也试过udev trigger 正如在这个答案中看到的那样。它还会将组更改为adm，但重启后也不会“保留”。我应该将规则置于/lib而不是 之下吗/etc？感觉不对。
