Hello, I do have an old laptop. I installed a minimal system without any network manager. Now if there is no network cable plugged in during boot time systemd hangs forever at the network interface part.
I just have the most simplistic /etc/network/interfaces ========== sources /etc/network/interfaces.d/ auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet dhcp ========================= there is no script in /etc/network/interfaces.d/ -- Henning Follmann | hfollm...@itcfollmann.com
