For pagekite.net, I am currently experimenting with bootstrapping and configuring servers using shell scripts built/configured using a #jinja static site generator.
If this works well (so far, it does), it replaces #Ansible ...
Servers are assigned an unguessable URL, from which they download both initial bootstrapping, updates and config. The web server is 100% static.
A sweet touch: while developing, the files just live on my laptop and are downloaded over #pagekite. Because why not?
