Bug Description

Hi,

When starting a virtual machine with the following command line :

qemu-system-x86_64 -k fr -m 1024 -smp 1 -display none \
 -rtc base=utc -daemonize \
 -drive if=none,file="my.qcow2",id=hd0 \
 -device virtio-blk,drive=hd0 \
 -netdev user,id=user.0,hostfwd=tcp::32768-:22,dnssearch=dns.companyname.com \
 -device virtio-net,netdev=user.0,mac=de:ad:de:01:02:03 \
 -vga none

The system-network doesn't take into account search domain and then search fail.

The same setup does work when using NetworkManager.

I could reproduce this trivially; a simple netplan config:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp: yes

Will show that my domain "cyphermox.net" here is not passed from DHCP in networkd to resolved (and does not show in /run/systemd/resolve/stub-resolv.conf or resolv.conf), whereas if I switch the renderer to "NetworkManager", I can then see both ~. and "cyphermox.net" in search domains when running 'systemd-resolve --status'.
