[clue] Juju.

Q, 
"I was able to get my PXE and chef stuff going in just over a day,"

Looks like a good presentation topic.  ;-)

 I looked at it real hard for deploying an openstack cluster about 2 years ago. I found juju to be interesting, but it required a lot of underlying tools to make it usable for my application (notably MAAS, which was also really cool, but overkill for my needs) and the charms, frankly, didn't work for me. If you want to do exactly what they do, they work as advertised. If not, it's "yet another thing to learn", and it's not trivial. I ended up replacing the whole thing with some simple PXE boot stuff and some shell scripts. I probably could have gotten juju to do what I wanted, but it would have taken me weeks, when the initial setup and eval also took weeks, and I was able to get my PXE and chef stuff going in just over a day, sooo, I dunno.
I suppose if you have a use case that meshes well with it, have nothing else in place, and have enough stuff going on to justify the setup investment, it could be a cool system, but it's far from light. The visual service deployment stuff is certainly neat, but I don't see that it provides a lot of value.

Does anyone have any experience with Juju?  https://jujucharms.com/

I asked on BLUG about CM tools for managing a single server. The answer was roughly, "salt, ansible,
whatever, just pick one".

Now I want to do that on a laptop as well.  And I think I'll pick propeller or slaughter.  Probably
propeller because Joey Hess and Haskell.

The hard part though isn't building a config with these tools (at least it shouldn't be at my
stage), it's having a clue what the end looks like and learning enough to figure out the steps.

For example, bootstrapping, which has to come before CM.  There's pre-seeding with d-i, but for
Raspbian I built an image file using debootstrap and some cool formatting tools.  Oh, I guess I
should figure out full disk encryption too at some point.

Anyhow, Juju looks like it pays more attention to services cooperating with each other (so maybe I
can get rid of my dual mysql installs?).  But it also seems to be Ubuntu specific and controlled by
Canonical.  So I'm not going to look at it unless someone says it's the bee's knees or I learn
enough to know it solves a problem I have.
