当我在终端中运行 snap 应用程序时，如下所示：
/usr/bin/snap run shadowsocks-rust.ssserver -c /etc/shadowsocks-rust/config.json
我看到了日志：
2023-05-14T18:55:11.714373725+03:00 INFO shadowsocks server 1.15.3 build 2023-03-12T16:38:32.068195882+00:00
2023-05-14T18:55:11.715955767+03:00 INFO shadowsocks tcp server listening on 0.0.0.0:12345, inbound address 0.0.0.0:12345
但是当我以 systemd 服务形式运行相同的程序时：
[Unit]
Description=shadowsocks service
After=network-online.target
[Service]
User=myuser
ExecStart=/usr/bin/snap run shadowsocks-rust.ssserver -c /etc/shadowsocks-rust/config.json
Restart=always
[Install]
WantedBy=multi-user.target
我看到的唯一日志来自 systemd( journalctl -u shadowsocks.service)：
May 14 18:37:08 mypc systemd[1]: Started shadowsocks service.
服务状态：
# systemctl status shadowsocks.service
● shadowsocks.service - shadowsocks service

如何让 journalctl 显示作为 systemd 服务运行的 snap 的日志？
