Draft: feat(images): add nixos-cnix-tty image for TTY activity
What?
Build a special image to be deployed on the PIE for the TTY activity.
Why?
The goal of this image is to provided a constrained environment on which students are invited to solve exercises in a shell using only their keyboard.
Hopefully, by using the keyboard they will get to know better shortcuts and command line utilities allowing them to be more efficient during the Piscine (they tend to rely on the mouse a lot!).
How?
- Preserve the foundation of NixOS PIE
- Disable unneeded features
- Display guidance on the screen to make students more comfortable with this environment.
- (optional) Preload the container image to avoid bandwidth issues.
