NixOS Image build scripts

[NixOS](http://nixos.org) is a linux distribution with a purely functional

package manager.

These scripts build .box images that can be used by [vagrant](http://vagrantup.com) for development, and other images suitable for production.
|
||||
|
||||
See [CycleSDK](https://bitbucket.org/oxdi/cycle-sdk) for the complete development environment (which makes use of the images generated here).
|
||||
These scripts build .box images that can be used by [vagrant](http://vagrantup.com) with the [vagrant-nixos](http://github.com/oxdi/vagrant-nixos) plugin for development, and other images suitable for production.

Updating the public box image

-----------------------------

`s3put` is handy tool for copying files to Amazon S3, it's part of the [boto](https://github.com/boto/boto) library.
|

|
||||
Install boto:
|
||||
|
||||
```bash
|
||||
pip install boto
|
||||
vagrant box add nixos-14.02-x86_64 nixos-14.02-x86_64-virtualbox.box

Push the .box image to S3 via s3put
|

Using the images
|

----------------
|
||||
|
||||
Vagrant does not have a nixos guest plugin by default, so you'll need to install [vagrant-nixos](http://github.com/oxdi/vagrant-nixos).
|
||||
|
||||
```bash
|
||||
s3put -a $AWS_ID -s $AWS_KEY -b oxdi -g public-read --prefix `pwd` cycle-xx.xx-x86_64-virtualbox.box
|
||||
vagrant plugin install vagrant-nixos
|
||||
vagrant init nixos-14.02-x86_64
|
||||
vagrant up
|
||||
```
|
||||
|
||||
The box will then be available at http://amazonaws.com/oxdi/cycle64-virtualbox.box
