Dear Maintainer,

The default network configuration for Debian is ifupdown after running
debian-installer, however systemd network-online.target by default does
not wait for ifupdown-wait-online.service.

sudo systemctl enable ifupdown-wait-online.service

after installation makes the desired effect but before doing this
network services start before DHCP is completed.

Shouldn't the default to be to enable ifupdown-wait-online.service ?
