dependency failed for pNFS block layout mapping daemon

[Peter Goodall]

> lsb_release -rd
Description: Ubuntu 16.04.3 LTS
Release: 16.04

I believe the package is: nfs-kernel-server

my boot screen reports:

dependency failed for pNFS block layout mapping daemon.

If I ask for status on the service I get:

```
nfs-blkmap.service - pNFS block layout mapping daemon
   Loaded: loaded (/lib/systemd/system/nfs-blkmap.service; static; vendor preset: enabled)
   Active: inactive (dead)
```

if I enter `sudo dmesg | grep -i depe ` I get:

```
...
[ 3.389944] systemd[1]: Dependency failed for pNFS block layout mapping daemon.
[ 3.389973] systemd[1]: nfs-blkmap.service: Job nfs-blkmap.service/start failed with result 'dependency'.

```
looks very similar to problem reported in:
