매개변수를 사용하여 udev에서 systemd 서비스를 (올바르게) 호출하는 방법은 무엇입니까?

USB 저장 장치가 연결되어 있을 때 udev에서 systemd 서비스를 트리거하고 장치 정보(이름)를 내 서비스에 전달하여 이를 스크립트에 제공하려고 합니다.

udev 규칙( /etc/udev/rules.d/99-foo.rules)을 만들었습니다.

ACTION=="add", KERNEL=="sd?", SUBSYSTEM=="block", ENV{ID_BUS}=="usb", TAG+="systemd", PROGRAM="/bin/systemd-escape -p %k", ENV{SYSTEMD_WANTS}+="bar@%c.service"

내 시스템 서비스( /etc/systemd/system/bar.service)는 비교적 기본적입니다.

[Unit]
Description=Script to do stuff with inserted device.

[Service]
Type=oneshot
ExecStart=/root/bin/usbhook %I

[Install]
WantedBy=multi-user.target

USB 드라이브가 연결되어 있는지 확인하면 /var/log/syslog드라이브가 컴퓨터에서 인식되지만 내 systemd 서비스가 시작되지 않습니다.

저는 udev 규칙과 systemd 스크립트가 제대로 작동할 것이라고 믿습니다. 인수를 전달하지 않는 udev 규칙을 바꾸면 ACTION=="add", KERNEL=="sd?", SUBSYSTEM=="block", ENV{ID_BUS}=="usb", TAG+="systemd", ENV{SYSTEMD_WANTS}+="bar.service"systemd 스크립트가 시작됩니다.
