Systemd 명령이 실패하는데 수동으로 실행할 수 있는 이유는 무엇입니까?

문제 없이 셸에서 다음 명령을 실행할 수 있습니다.

sudo -u ktrl /home/andrew/.cargo/bin/ktrl -d /dev/input/event3

그러나 내가 봉사하려고 할 때:

/etc/systemd/system/ktrl.service

[Unit]
Description=ktrl

[Service]
User=ktrl
Environment=HOME=/opt/ktrl
ExecStart=/home/andrew/.cargo/bin/ktrl -d /dev/input/event3
  
[Install]
WantedBy=multi-user.target

다음 오류가 발생합니다.systemctl status ktrl.service

Andrew 로 명령을 실행하고 있습니다 sudo -u ktrl /home/andrew/.cargo/bin/ktrl -d /dev/input/event3. 그러나 ktrl로 전환 sudo su ktrl하고 명령을 실행 해도 /home/andrew/.cargo/bin/ktrl -d /dev/input/event3여전히 작동합니다 .
