What about using Nix(OS)? This would be the config for Heinrich: https://gist.github.com/aszlig/74d0d772a352e621902e

NixOS:

• There is no heinrich anymore, but a Odroid
• Some things are not covered by the config
  • VPN is now made by a bash script checking for ip changes and managing routing
  • DHCP and DNS must be handled by dnsmasq
  • Perl script making live statistics about active devices
  • ipv6 radvd daemon
  • OLSRd making routing to hotelturm, mo and other servers in internet via VPN
• No knowledge of admins about NixOS, at least on Odroid

Make changes trackable:

• All config files will be moved to /config and gitted there
• A push to github is not possible cause of security; maybe we can do a /config/security not pushing... But I think this would be an security issue if someone not knowing what he is doing. I will push it to a private git server by my own.
