As the kernel is not configured with namespace support,and systemd looks for network namespace..I missed that patch.
I will add it.

Thanks @ratagupt

[ratagupt]

workaround is:-
1) to comment the following line in the "/lib/systemd/system/systemd-hostnamed.service"
```[Unit]
Description=Hostname Service
Documentation=man:systemd-hostnamed.service(8) man:hostname(5) man:machine-info(5)

BusName=org.freedesktop.hostname1
WatchdogSec=3min

```
2) systemctl daemon-reload
3) systemctl restart xyz.openbmc_project.Network.service.

@sivassrr @gkeishin Even our xyz network test cases failing because of this.
But works on workaround patch given by @ratagupt

[rfrandse]

https://gerrit.openbmc-project.xyz/5398 Don't return the error if unable to create the network namespace

Verified working on latest build

For those that need this, follow the steps below:

1. systemctl edit systemd-hostnamed

   Add the 2 lines below then exit the editor (don't forget to save when prompted):

   [Service]
   PrivateNetwork=no

2. This will create an override.conf file with the above 2 lines in the directory:

   /etc/systemd/system/systemd-hostnamed.service.d/

3. The update systemd:

   systemctl daemon-reload

4. Then restart the service:

   systemctl restart systemd-hostnamed

You should now be able to run hostnamectl without it hanging.

The above suggestions do work, but don't do that!

Instead enable CONFIG_NET_NS - if you don't you will have other strange errors, for example pulseaudio won't work (will freeze on startup), and errors like rtkit-daemon.service: Failed at step NETWORK spawning /usr/lib/rtkit/rtkit-daemon: Invalid argument
