Hello,

I found different ways to define the hostname ...

this HOSTNAME=3D"host.domain.tld"

or this: HOSTNAME=3D"host" DOMAIN=3D"domain.tld"

what is the correct way?

Thanks, Walter

In the case of RHEL 5 and 6 the former way is recommended[1]. I don't know whether that advice has changed with RHEL 7.
