<p class="MsoNormal">Set the hostname by making a tmp file with the 'network' kickstart command in the %pre script like this:<br>
echo "network --device=ens192 --hostname=${HOSTNAME}" > /tmp/ks-network-hostname<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">then include that file in the kickstart commands section of the file like this:<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Overwriting the files like you're doing is a blunt instrument and is sure to fail at some point (like you're seeing). Use the kickstart commands as much as possible so anaconda can do the right thing. I also
treat every major release as a *major* release, which requires a complete review and rewrite to adapt to whatever changes were made.<o:p></o:p></p>
