[Bug 1763650] [NEW] Suspend/Resume cycle changes advertised hostname (loss of name resolution)

[TJ]

Public bug reported:

On 16.04 and 18.04 hosts on my LAN I've been suffering intermittent loss
of mDNS resolution after devices have been suspended and resumed.

Today I decided to investigate and noticed that on resume the hostname
being advertised is changed.

E.g.

hephaestion.local == Cold Boot
hephaestion-1.local == 1st suspend/resume
hephaestion-2.local == 2nd suspend/resume
...
etc.

It can be reset by restarting the service:

systemctl restart avahi-daemon

     Importance: Undecided

** Summary changed:

- Suspend/Resume cycle changes advertised hostname
+ Suspend/Resume cycle changes advertised hostname (loss of name resolution)
