/etc/nixos/configuration.nix

Readme_NIX_OS.md

My experiments with an XMonad setup in NixOS. This is my work box now, so it pretty much works.

probably needs:

# useradd -m iain
# passwd iain ...
# passwd root ...

configuration.nix

# This is a generated file.  Do not modify!
# Make changes to /etc/nixos/configuration.nix instead.

$ fdisk /dev/sdb (or whatever device you want to install on)

$ mkfs.ext4 -L nixos /dev/sdb1 (idem)

$ mkswap -L swap /dev/sdb2 (idem)

$ mount LABEL=nixos /mnt

$ nixos-option --install

• For a basic install: $ nano /mnt/etc/nixos/configuration.nix (in particular, set the fileSystems and swapDevices options)
• or, for this set of scripts: $ wget https://gist.github.com/i-e-b/6320077/raw/ecea4e02867e563406f4238a880783a161bee9ba/configuration.nix > /mnt/etc/nixos/configuration.nix
