[systemd-devel] systemd 225: cannot override nspawn service

[crequill]

In container boot with : systemd-nspawn -bD
/var/lib/machines/ci-container/ -n
        /sys/class/net show the host interfaces (enp3s1f0, ...)
        ip link show only the interfaces lo and host0 (as desired)

Perhaps it's why netctl doesn't see the host0 interface
