The way how I understand loopback entries in /etc/hosts should be the format:
127.0.0.1 localhost.localdomain localhost
But on some of my computers I will see:
127.0.0.1 localhost.localdomain <hostname> localhost
127.0.0.1 <hostname> localhost.localdomain localhost
Does anyone know why this is happening?
Should I keep the hostname in there or remove it??
