OP here, this is a set of scripts to run in a new VPS, to install some basic stuff that you'll need on every server, to create a new user with sudo powers, to disable root admin, install etckeeper, install and setup ufw firewall and then, as a user, somesupercharging like zsh with presto, clones your dotfiles, tmux... Finally a set of optional scripts to install additional software which doesn't install with a line-liner (apt-get install) but requires some combination of download, untar, compile (cmake or ./configure, make, make install...), or add a new repo and download...
Both suggestions to improve and pull requests are welcome.
