My dotfiles - including my vim, terminal and font configs.
Mostly focusing on setting things up on NixOS, but supporting other OSes where possible.

## bootstrap new machine with NixOS:

1. boot the target machine from the livecd
2. change password for the default user `nixos`
3. ssh from another, already bootstrapped, machine
