Comment 14 for bug 1627371

You will find a recipe to work around all bugs stopping the installation of freeipa with integrated DNS on 18.04/bionic as of this date. Hopefully folks who like to fix things can work these into the install scripts and programs.

At the heart of the timing problems (there are many others) is the install script's habit of (re) starting a service then nearly immediately placing calls to it (which fail as the service isn't up yet). 4 cores and 4GB of memory was enough to avoid all but two of the problems. The above note includes four lines of code in two files that inject waits until the system load is under 9% before processing further after starting a service.
