  + Configure on how the `history` works
  + Enable nicer `cd` and globbing behavior
  + Enable tab completion, even for aliases
  + Add some more stuff from Debian's ~/.bashrc
- Add ~/.bash_logout clearing the screen
- Adapt the installation script to remove
  possibly conflicting files
- Ensure ~/.local/state/bash/ exists
