+=== Bug fixes
+
+* Previously, `getFQDN()` relied on the fully-qualified domain name (FQDN) library to determine its FQDN, and the FQDN library tried to read the `/etc/hosts` folder directly. Consequently, on some {op-system-first} installations with uncommon DNS configurations, the FQDN library would fail to install and abort the installation. With this update, _mirror registry for Red Hat OpenShift_ uses `hostname` to determine the FQDN. As a result, the FQDN library does not fail to install. (link:https://issues.redhat.com/browse/PROJQUAY-4139[*PROJQUAY-4139*])
