Dear Fumiyasu, > Have you tried systemd-networkd-wait-online.service(8) Not really. I tried it briefly yesterday and the unit fails as it requires networkd.service which is not by default enabled in Debian Stretch. So, that doesn't help unless I migrate to networkd which I'm reluctant to do at this point.
> or ifupdown-wait-online.service? I don't have such a unit on my system. Searching the package repository for it shows it's currently only available in sid. Regards, Timo
