Issue

Anaconda on RHEL6 does not populate the public ip of the server and the hostname on /etc/hosts. This is documented here:

The /etc/hosts file is not populated with the hostname and IP in Red Hat Enterprise Linux 6

However, I don't understand if I'm ok to just add the entry manually there, like:

192.168.0.1 myhost myhost.mydomain.com

We don't use NetworkManager, just an old fashioned static ip config.

Environment

Red Hat Enterprise Linux (RHEL) 6
Static ip address
