Aqui está o meu arquivo de unidade de um serviço systemd:
[Unit]
Description=Tunnel For %i
After=network.target
[Service]
User=autossh
ExecStart=/usr/bin/autossh -M 0 -N -o "ExitOnForwardFailure yes" -o "ConnectTimeout=1" -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -R 40443:installserver:40443 -R 8080:installserver:8080 tunnel@%i
Restart=always
[Install]
WantedBy=multi-user.target
A unidade falhou 15 dias atrás e o systemd não a reiniciou, embora "Reiniciar = sempre" esteja no arquivo de unidades acima.
Aqui a saída de status deste serviço:
salt:/srv # systemctl status autossh@eins-work

Como configurar um serviço systemd para sempre reiniciar se algo falhar?
