 (For the future) Once NetBSD has decent support for Amazon EC2, we will publish the AMI identifiers so you can quickly boot up in a NetBSD environment without going through all the steps given below.
 
-## Fetch and build the operating system
+## Fetch and build NetBSD
 
-## Customizations
+EC2 does not provide direct access to console. As a consequence, we cannot rely on it for installation, especially via [[!template id=man name=sysinst section=8]]. We must therefore build and install NetBSD in a separate directory, and configure it manually, before upload.
 
-### For EC2
+This tutorial assumes that you will build the system under **/mnt/ec2**.
 
-### For your own needs
+/!\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.
 
+XXX build and install /mnt/ec2
+
+## Configuration
+
+/!\This part assumes that you have a non-configured NetBSD system extracted under **/mnt/ec2**; that is, it should have not been modified through [[!template id=man name=sysinst section=8]], nor by you.
+
+Under **/mnt/ec2**, edit the files to add (or modify) these lines:
+
+[[!template id=filecontent name=etc/rc.conf text="""
+rc_configured=YES
+
+hostname=NetBSD-EC2-$(uname -m)
+sshd=YES # for remote shell access to instance
+"""]]
+
+[[!template id=filecontent name=etc/ssh/sshd_config text="""
+# Allows root to login via authentication keys
+PermitRootLogin without-password
+"""]]
+
+Create **etc/fstab** and etc/ifconfig.xennet0**:
+
+[[!template id=filecontent name=etc/fstab text="""
+/dev/xbd1a /        ffs    rw 1 1
+/dev/xbd0a /grub    ext2   rw 2 2
+kernfs     /kern    kernfs rw
+ptyfs      /dev/pts ptyfs  rw
+procfs     /proc    procfs rw
+"""]]
+
+[[!template id=filecontent name=etc/ifconfig.xennet0 text="""
+# Configure interface for EC2 network
+dhcp
+"""]]
+
+Once done, you can modify the system living under **/mnt/ec2** to fit your needs (adding custom binaries, packages, etc).
 
 ## Upload your OS
 
+When the NetBSD is properly installed and configured, we have to upload it to EC2. For that, we will have to create a minimalist EC2 instance, to which we will upload our files to construct our snapshots.
