Change hosts file(temporary) without rebuild

Help
1

Hi, is it possibly to change the hosts file without rebuilding the whole system?
I’m a pentester and when connecting to test machines it is very convenient to have a hostname. Since it is often needed it would be a lot of effort to always rebuild the system.

You can probably set environment.etc.hosts.enable = false; and then write /etc/hosts yourself.

Thanks i did not knew that there were such options in nixos.
You’re answer inspired me to use environment.etc.hosts.mode = "0700";, which will copy the file instead of symlinking it. So the default config will be written to it but I can also change it anytime

Always worth checking out what happens under the hood when you want to do something that doesn’t seem directly supported by the module you are using.
