I wrote a primer script to prep a RamNode VPS with Debian for use as a webhead (or whatever). It will result in a system that's secure, firewalled, tuned, and has repositories for dotdeb (PHP7, Redis, etc.) and tuxhelp (Hiawatha webserver) ready to use. It's what I use when I setup one-off hosted Hiawatha servers for folks. Wrote a quick about it
here [dotbalm.org] if anybody's interested.
