Introduction

You will need a few Gigabytes to have enough pace for kernel compiling and storing all the binary packages and iso image.

This page is divided into 2 main sections

Create a build environment
Update a existing environment

Create a build environment

The Build Environment (called BE from now on) could be any of the following...

Created on a existing 2.6 kernel
A disk-based Alpine

Create BE on existing 2.6 kernel

Create BE on HD-based Alpine

First you need to boot a alpine-test.iso
Ether you do it on a standalone computer or in a virtual machine.

Preparing KVM (temporary notes)

I chose to setup a HD-based Alpine in a virtual machine on my Ubuntu 8.10.
(Notes: This section about setting up KVM should probably be removed later on - it's mostly there to help me get started).

apt-get install kvm ###This installs KVM###
kvm-img create alpine-kvm_hd.img 5G ###Create a KVM-disk###
wget http://distrib-coffee.ipsl.jussieu.fr/pub/linux/alpine/alpine/v1.9/alpine-test.iso ###Download iso###

Before we boot our kvm-qemu we need to prepare it for networking by following the Running_Alpinelinux_As_a_QEMU_networked_Guest documents.
This assumes you created a file qemu-ifup according to the wiki-doc just mentioned.

sudo kvm -cdrom alpine-test.iso -boot d -net nic,vlan=0 -net tap,vlan=0,ifname=tap0,script=./qemu-ifup alpine-kvm_hd.img

At this point we started a virtual machine running a clean Alpine.
Now we need to prepare this for networking, etc.

Temporary note: For some reason I can't get networking to work in my kvm-qemu box. Complaining about tun/tap on my host. Need to fix this.

Prepare the clean Alpine

At this point you should have a fresh alpine-box.
