hostnamed should not print warning about nss-myhostname

[Marc Deslauriers]

Currently hostnamed prints the following error in syslog:

systemd-hostnamed[24508]: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolveable. Please install nss-myhostname!

Since nss-myhostname was rejected as being the right approach in https://bugs.launchpad.net/ubuntu/+source/libnss-myhostname/+bug/1162478/comments/6 , we should not print the warning message in the LTS release, even if hostnamed doesn't currently modify /etc/hosts (LP: #1162475).

Can we please patch this warning out to prevent users from thinking something is wrong on their system and leading them to install libnss-myhostname?

Status changed to 'Confirmed' because the bug affects multiple users.

[Josh (majik)]

Problem continues to exist on 14.10.

[Spectrumknight (spectrumknight)]

still having this awkward warning...

[Marcus (elect-tech)]

 It is still affecting 14.04LTS. Is this opening any security holes?

This is _not_ a duplicate of bug #1162475 (titled "Changing hostname doesn't update /etc/hosts")

[Martin Wildam (mwildam)]

Ubuntu 14.04 with latest patchlevel - I still notice that message and indeed thought, something is rotten.
