+* to setup
+** get a machine and install Nixos on it (any configuration it says)
+** add machine configuration to [[https://code.hackerspace.pl/hswaw/hscloud/src/branch/master/cluster/machines|cluster/machines directory]]
+**
+===selected difficulties===
+* NixOS is not easily dockerizable because the privilage model requires a special daemon which runs as root. This should instead run as a non root nix user and give access through that
+* If you install two bootloaders, one by accident first which ends up with priority, NixOS silently respects that and doesn't place it's own bootloader to run, which means changes don't take effect
+* Not clear about NixOS debugging - never managed to get prompt inside the machine
