We want to start up an IRC client whenever a user logs into/starts their session.

It is possible to find a variety of different ways to do this, but a simple modern approach that fits well within NixOS's ~~{{declarative~~ model}} is to declare a {{ic|systemd}} unit which initializes the IRC client upon session login by a user.

It is possible to find a variety of different ways to do this, but a simple modern approach that fits well within NixOS's [[Declarative model]] is to declare a {{ic|systemd}} unit which initializes the IRC client upon session login by a user.

Assume that our IRC client is {{ic|irssi}} as the IRC client. We'll run it inside a [https://wiki.archlinux.org/title/GNU_Screen screen] daemon, which apart from allowing us to [https://en.wikipedia.org/wiki/Terminal_multiplexer multiplex] our terminal sessions, also enables the IRC session to continue even after we log out of our shell session.
