I would like to know more about Juju cache.
After I start a charm and Juju provisions a machine for the first time, the charm will be downloaded and all dependencies installed (apt-get, etc). This process can be very long.
Once the charm has been build, configured and deployed once, can JuJu provision more instances of the same charm pre-built and configured?
I presume that's what the cache is for, but the documentation is not very explicit: https://jujucharms.com/docs/stable/charms-deploying
How does Juju tracks the state of the charm if it works that way?
