Thanks for the reply. I don’t recall “dryrun” mode being mentioned, although I do remember the disclaimer that 20 to 40 minutes was normal in real life. I was seeing times longer than that but I suspect it is partly due to slow networking here and VMware running poorly on my memory constrained laptop.
Sasha explained that subsequent service stops and starts are also slow in order to be “safe”. I was expecting slow installs but less-slow service stops and starts and I stand corrected here too.
