 ### Nixos
+With teh package manager we are able to create packages in a deterministic manner and store them in a way that does not suffer path conflicts.  
+
+Some (possibly crazy) folks saw this and decided to apply this to an entire operating system.  
+The advantages are clear, the required programs are added to teh path for teh current iteration of the system.  
+If any error arises the system can be rolled back to a previous config.
+
+Configuration is done via ``*.nix`` files, which are then converted into teh native config for the application in question.  
+
+For example [this file][nix_dns] turns a list of attributes.  
+```nix
+{
+    record = "forgejo";
+    r_type = "CNAME";
+    value = "glados.skynet.ie";
+}
+```
+Into a config usable by the BIND DNS server.
