## DNS
Zatím nevím, proč nefunguje korektně. Nastavím `/etc/resolv.conf` ručně.  
bylo: `resolv.conf -> ../run/systemd/resolve/stub-resolv.conf`
    ```shell
    sudo -i
    rm -f /etc/resolv.conf
    cat > /etc/resolv.conf << EOF
    nameserver 192.168.88.101
    nameserver 192.168.88.1
    domain habad.eu
    search habad.eu
    EOF
    ```
