What were you trying to do that didn't work?

Running 'hostname -f' or 'dnsdomainname' in RHEL-10 can only print hostname but not fqdn.

Please provide the package NVR for which bug is seen:

hostname-3.23-12.el10.x86_64

How reproducible:

100%

Steps to Reproduce:

1. Start a VM on Azure.

2. Check fqdn: # hostname -f

Actual results:

It only prints hostname but not fqdn:

1. hostname -f
   wala10newtest105230906-vm1

When I search for my hostname on DNS it can print the fqdn:

1. nslookup `hostname`
   Server: 168.63.129.16
   Address: 168.63.129.16#53

Non-authoritative answer:
Name: wala10newtest105230906-vm1.hz1j3miw15lupck5xokl3wb4cg.bx.internal.cloudapp.net
Address: 10.0.0.4

In RHEL-9.5 it can print the fqdn:

$ hostname -f
wala90kernel94armv6-vm2.s0ndvlc20tne5p0z3k5ck253hb.xx.internal.cloudapp.net

Expected results:

Running 'hostname -f' can print fqdn.
