Joseph, Can you please explain more detail?
Are you saying that you setup /etc/hosts with two ethernet entries (one for public and one for private) and the 127.0.0.1 line before oscar installation but oscar removed the public one after installation? And also, the 127.0.0.1 line did not have the FQDN before but OSCAR added it after the installation? If these things happened, this is a bug of OSCAR 5.1 and we will fix it ASAP.
