How can I change the hostname?

[luochen1990]

I find that setting networking.hostName only works after sudo nixos-rebuild switch, and when I reboot the wsl with wsl --shutdown, it turn back to the Windows hostname again.

So, am I expected to keep the hostname and not touching it ?

The hostname is set by WSL on boot. You can create a file /etc/wsl.conf with the following contents to set a custom hostname:

[network]
hostname = yournewname

It's not super well documented though, so I don't know if it has some other side-effects.

Maybe it makes sense to manage /etc/wsl.conf through NixOS-WSL after modularisation (#10 / #19) is done? 🤔

This is now possible through wsl.wslConf.network.hostname

Shouldn't wsl.wslConf.network.hostname be derived from networking.hostName?

@Atry It is
