piku-bootstrap script for provisioning a server with piku.py (#23)
* Bootstrap script initial working version. * Bootstrap: more verbose messaging. * Bootstrap: working up to piku over SSH. * Bootstrap: full bootstrap minus nginx. * Bootstrap: ensure py2 for Ansible. * Bootstrap: more deps. * Bootstrap: piku user Ansible tmp to avoid err. * Bootstrap: local venv source in ~/.piku-bootstrap * Bootstrap: nginx + incron install. * Bootstrap: self-install logging and less verbose. * Bootstrap: special permissions for --pi mode. * Improved usage + self-install text.pull/41/head
