How do I modify my hosts file in Nixos?

Clash Royale CLAN TAG#URR8PPP

Seems my hosts file (/etc/hosts) points to /nix/store/gds7bha3bx0a22pnzw93pgf0666anpyr-etc-hosts and is read only.

How am I meant to modify this file?

Modify the nixos config with:

networking.extraHosts =
 ''
 127.0.0.2 other-localhost
 10.0.0.1 server
 '';

It sounds like it could be an answer; perhaps Chris could use some extra words to explain what this is and why it works?

Perhaps a reference could be github.com/NixOS/nixpkgs/blob/master/nixos/modules/config/…

When I reviewing, I thought that it looked like a fairly random piece of data. It is clear that is has something to do with the code at the GitHub link that Jeff posted in an earlier comment, but it looks malformed (or I just don't understand the the syntax, which appears different from the GitHub code). If this is a proper answer, please add information about where and how and why this code snipped would be used. Until then, I will still consider this to be a non-answer. If it's a clarification to the question, then please update the question with this info and describe how it's relevant.

Well, yes, networking.extraHosts from the configuration.nix file will get into the /etc/hosts on the resulting NixOS system.
