 This tutorial aims at showing how you can build, setup, upload and launch NetBSD under the [Amazon EC2](http://aws.amazon.com/ec2/) service.  This tutorial aims at showing how you can build, setup, upload and launch NetBSD under the [Amazon EC2](http://aws.amazon.com/ec2/) service. We will first give some brief explanations on how you can obtain an AWS account, and what you will need to run NetBSD under EC2. Then, at your convenience, you will be able to start with pre-made images, or roll-out your own.

 /!\Please note that you will need the [[!template id=man name=makefs section=8]] tool later in the process, so you can build a file system image that can be uploaded to Amazon EC2. You are therefore advised to perform the installation directly under a living NetBSD system, or in case your are not, to [[fetch the source|fetching_src]] to build the toolchain that will contain the **nbmakefs** utility.  /!\Please note that you will need the [[!template id=man name=makefs section=8]] tool later in the process, so you can build a file system image that can be uploaded to Amazon EC2.

 XXX build and install /mnt/ec2  [Details regarding on how you can fetch *src* are given in the NetBSD's guide](http://www.netbsd.org/docs/guide/en/chap-fetch.html). Here are the basic commands you should type to build and install NetBSD under */mnt/ec2*:

 Create *etc/fstab* and *etc/ifconfig.xennet0*:  This file is needed if you want to login via the SSH key pair created previously:

 You can then proceed to modifying the system living under */mnt/ec2*, so it can fit your needs (adding custom binaries, packages, etc). When done, build the *NetBSD-AMI.img* ffs image, via [[!template id=man name=makefs section=8]], or **nbmakefs**, from the [toolchain](http://www.netbsd.org/docs/guide/en/chap-build.html#chap-build-tools):  You can then proceed to modifying the system living under */mnt/ec2*, so it can fit your needs (adding custom binaries, packages, etc).
