## Fix NFS Mount at Boot

### Use these options (Debian 10):

`noauto,x-systemd.automount,_netdev`

This forces systemd to take over auto-mounting responsibilites.

Just using \_netdev alone fails to mount at boot; i.e.: 'network unreachable' - or - 'dependency failed'

### Example fstab

{% code title="/etc/fstab" %}

```bash
10.0.0.1:/mountpoint  /mountpoint  nfs  noauto,x-systemd.automount,_netdev,rw,hard,intr,timeo=14,tcp,noatime  0 0
```

{% endcode %}
