#REDIRECT [[Alpine Linux in a chroot]]
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|Create a build environment]]
 
* [[#Update a existing environment|Update a existing environment]]
 
 
 
= Create a build environment =
 
 
 
The Build Environment (called [[#Create a build environment|BE]] from now on) could be any of the following...
 
* Created on a existing 2.6 kernel
 
* A [[Native Harddisk Install|disk-based Alpine]]
 
 
 
== Create [[#Create a build environment|BE]] on existing 2.6 kernel ==
 
 
 
== Create [[#Create a build environment|BE]] on HD-based Alpine ==
 
First you need to boot a alpine-test.iso<BR>
 
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.<BR>
 
('''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.<BR>
 
This assumes you created a file '''qemu-ifup''' according to the wiki-doc just mentioned.
 
sudo kvm -cdrom alpine-test.iso -boot d -net tap,vlan=0,ifname=tap0,script=./qemu-ifup -net nic,vlan0 alpine-kvm_hd.img
 
 
 
At this point we started a virtual machine running a clean Alpine.<BR>
 
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.<BR>
