yup, that's where i'm at. which i pretty much the same place i was at when
i admin'd a cluster eight years ago.
i like ansible as a idempotent library for scripting (way better than the
shell scripts we used to use), but it was worth a try to be able to fiddle
something on my dev machine and run single local command that would take
care of all the hosts and ssh'ing and everything and just get the stuff
where it needs to be.
maybe in another eight years ;)
