The services are now active by default and do not need to be activated after IPA has been deployed. The fixnet service is always activated and removes all lines containing the hostname from /etc/hosts and adds a new line with the IP and the hostname with and without domain. If IPA is deployed with DNS (the config file /etc/named.conf exists and there is a '^dyndb "ipa"' line in /etc/named.conf) then /etc/resolv.conf is also changed to use the local DNS server. The fixipaip service is now also always activated, but only started IF IPA has been deployed and the ipa service was started before. infra/image/build.sh is not actvating the services anymore, the services are now actiavted in alll dockerfiles.
