Amigos, Boa tarde

OS: Linux Mint 19.1 32bit

Preciso que o hwclock.service abaixo rode logo apos todo serviço network seja carregado,
o paramento "After=NetworkManager-wait-online.service" que estou utilizando esta correto?

# cat /lib/systemd/system/hwclock.service
[Unit]
Description=Hardware Clock Synchronization
After=NetworkManager-wait-online.service
Wants=NetworkManager-wait-online.service

[Service]
ExecStart= /root/script/hwclock.sh
ExecStop= /sbin/hwclock --systohc --utc --adjfile=/etc/adjtime

[Install]
WantedBy=multi-user.target

Obrigado,

Aparentemente, o serviço funcionará corretamente se o sistema utiliza NetworkManager, pois NetworkManager-wait-online.service é específico. Uma alternativa mais genérica seria utilizar network-online.target ao invés de NetworkManager-wait-online.service, para casos onde seja utilizado systemd-networkd, connman ou outros.

Uma referência interessante: https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

FurretUber, Bom dia

Obrigado pelo seu retorno, o linux mint não utiliza o serviço systemd-networkd, pelo menos nos teste que realizei!!!
